Prep your blender: Add liquids first to help the blades catch. Pour in coconut or almond milk, then lime juice.
Layer the bases: Add Greek yogurt, protein powder, and oats (if using). This keeps powders from clumping at the top.
Add fruit and seeds: Drop in frozen mango, frozen pineapple, banana, and chia seeds.
If using shredded coconut, add it now.
Blend on low, then high: Start on low speed for 10–15 seconds, then blend on high until smooth and creamy, about 30–45 seconds. Scrape down the sides if needed.
Adjust thickness: For a thinner smoothie, add a splash more milk. For a thicker texture, add a little more frozen fruit or a few ice cubes.
Taste and fine-tune: Sip and adjust sweetness.
If the fruit isn’t very ripe, add a teaspoon of honey or maple. If it’s too sweet, add a little extra lime juice.
Serve right away: Pour into a chilled glass or an insulated cup. Top with a sprinkle of coconut or extra chia for texture.
