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.
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.
Flake the tuna: Drain the tuna well. Use a fork to break it into chunks, keeping some larger pieces for texture.
Add the veggies: Stir in cherry tomatoes, cucumber, and red onion.
If using capers or pickles, add them now for a briny pop.
Make a quick dressing: In a small cup, whisk olive oil, lemon juice, Dijon, salt, and pepper. Taste and adjust acid and seasoning.
Combine gently: Add the avocado and herbs to the bowl, pour over the dressing, and toss lightly so the avocado stays intact.
Finish with crunch and heat: Sprinkle pumpkin seeds or almonds on top. Add red pepper flakes if you like a little heat.
Taste and tweak: Add more lemon, salt, or pepper if needed.
Serve immediately.
