Ingredients

  

• 1 ripe avocado, diced
• 1 can tuna (5–6 oz), drained; choose water-packed for leaner or olive oil-packed for richer flavor
• 1/2 cup cherry tomatoes, halved
• 1/3 cup cucumber, diced
• 2 tablespoons red onion, finely chopped
• 1 tablespoon capers or chopped pickles (optional, for tang)
• 1–2 tablespoons fresh herbs like parsley, dill, or cilantro, chopped
• 1 tablespoon extra-virgin olive oil
• 1–2 teaspoons lemon juice (plus extra to taste)
• 1/2 teaspoon Dijon mustard (optional, for a little kick)
• Salt and black pepper to taste
• Red pepper flakes (optional)
• 1/2 cup cooked quinoa or brown rice (optional, for a heartier bowl)
• 2 tablespoons pumpkin seeds or toasted almonds (optional, for crunch)
• Greens like arugula, spinach, or spring mix, a small handful (optional)

Method

 

1. Prep the base: If using greens or grains, add them to your bowl first. This creates a sturdy base that soaks up the dressing and juices.
2. Dice the avocado: Cut the avocado into bite-sized cubes. Toss gently with a squeeze of lemon and a pinch of salt to keep it bright and flavorful.
3. Flake the tuna: Drain the tuna well. Use a fork to break it into chunks, keeping some larger pieces for texture.
4. Add the veggies: Stir in cherry tomatoes, cucumber, and red onion. If using capers or pickles, add them now for a briny pop.
5. Make a quick dressing: In a small cup, whisk olive oil, lemon juice, Dijon, salt, and pepper. Taste and adjust acid and seasoning.
6. Combine gently: Add the avocado and herbs to the bowl, pour over the dressing, and toss lightly so the avocado stays intact.
7. Finish with crunch and heat: Sprinkle pumpkin seeds or almonds on top. Add red pepper flakes if you like a little heat.
8. Taste and tweak: Add more lemon, salt, or pepper if needed. Serve immediately.

How to Store

This bowl is best fresh because avocado browns and softens quickly. If you need to prep ahead, store components separately. Keep the tuna mixture and chopped veggies in an airtight container for up to 2 days, and cut the avocado right before serving.

For minimal browning, toss avocado with extra lemon and store tightly covered with plastic wrap pressed against the surface.

Keep the dressing in a small jar in the fridge and add it just before eating. Avoid freezing—textures won’t hold up.

Why This is Good for You

• High protein: Tuna offers a strong dose of lean protein to support muscle repair and steady energy.
• Healthy fats: Avocado and olive oil provide heart-healthy monounsaturated fats that help with satiety.
• Fiber and micronutrients: Veggies and optional grains add fiber, vitamins, minerals, and antioxidants.
• Balanced macros: Protein + healthy fats + fiber help keep blood sugar stable and curb cravings.
• Omega-3s: Tuna contains omega-3 fatty acids, which support brain and heart health.

What Not to Do

• Don’t skip draining the tuna: Excess liquid makes the bowl watery and dulls the flavor.
• Don’t overmix: Gentle tossing keeps the avocado from turning into mush.
• Don’t over-salt early: Capers, pickles, and tuna can be salty; season at the end after tasting.
• Don’t use an underripe avocado: It won’t give you the creamy texture that makes this bowl so satisfying.
• Don’t add hot grains directly: Let cooked quinoa or rice cool slightly so the avocado doesn’t soften too much.

Variations You Can Try

• Spicy Sriracha Bowl: Add a drizzle of sriracha or chili crisp and a squeeze of lime.
• Mediterranean Twist: Add Kalamata olives, feta crumbles, and oregano; swap lemon for red wine vinegar.
• Mexican-Inspired: Add corn, black beans, cilantro, and a pinch of cumin; finish with lime.
• Egg Boost: Top with a soft-boiled or poached egg for extra protein and richness.
• Grain-Free Crunch: Skip grains and add extra seeds, shredded cabbage, or radishes for texture.
• Greek Yogurt Dressing: Blend 1–2 tablespoons Greek yogurt into the dressing for creaminess and even more protein.
• Swap the Protein: Use canned salmon, leftover grilled chicken, or chickpeas for a different profile.

FAQ

Can I use tuna in olive oil instead of water-packed?

Yes. Olive oil–packed tuna adds richer flavor and a more luxurious texture.

If you use it, reduce or skip the extra olive oil in the dressing so the bowl doesn’t get greasy.

How can I make this dairy-free or gluten-free?

It’s naturally dairy-free and gluten-free as written. If you add grains, choose gluten-free options like quinoa or certified GF brown rice.

What if my avocado isn’t ripe?

Use a small scoop of store-bought guacamole or mash a slightly firm avocado with extra lemon and olive oil to soften the texture. It won’t be perfect, but it will still taste great.

Is this good for meal prep?

Yes, with a tweak.

Prep the tuna, veggies, and dressing in advance and store separately. Add avocado and dressing right before you eat to keep everything fresh and bright.

How much protein is in this bowl?

One can of tuna typically provides about 20–25 grams of protein. Add an egg or some Greek yogurt in the dressing to push it higher, or include quinoa for a balanced boost.

Can I make it without mustard?

Absolutely.

Skip the Dijon and rely on lemon, olive oil, salt, and pepper. You can add a splash of apple cider vinegar or a pinch of garlic powder for extra punch.

What greens work best?

Arugula, spinach, or spring mix all work well. Choose tender greens that won’t compete with the creamy avocado and flaked tuna.
