Fish tacos with avocado mango salsa may just become your new favorite 21 Day Fix recipe to celebrate Cinco de Mayo! Light, fresh fish and delicious mango salsa with just the right amount of heat, make these fish tacos perfect for any time you get that taco craving!



  • 12 oz of fish or shrimp
  • 4 corn tortillas (on the 21 day Fix, you can have 1 flour or TWO corn for a yellow.)
  • salt free taco seasoning
  • cilantro
  • 3 limes
  • 1 cup of diced mango
  • 2/3 cup diced avocado
  • 1/4 diced red onion
  • 1 tablespoon of diced jalapeƱo
  • 1/3 cup of plain Greek yogurt
  • shredded lettuce or cabbage
  • olive oil spray


  1. Marinate the fish in taco seasoning, juice from 1 lime and a small bunch of cilantro. Let sit for at least 20 minutes.
  2. Combine the mango through the diced red onion from the list of ingredients to make the salsa. Add juice from one lime and a tablespoon of chopped cilantro.
  3. Next, make the yogurt sauce. Add the juice from the last lime with the Greek yogurt. Add 1-2 tablespoons of diced cilantro and mix well.
  4. Grill fish until flaky and white. You could cook this on the stovetop, but I LOVE cooking fish outside. No smell or cleanup!!
  5. When the fish is cooked through, lightly spray the corn tortillas with olive oil and place on the top rack of the grill for a minute or so, just until warm and pliable. **If you get distracted by your 5 year old and leave them on too long, they will become tortilla chips. Just a warning!
  6. Assemble tacos while tortillas are warm. First, I spread the yogurt sauce, then add the cabbage or lettuce, fish, and top with the mango salsa. You do it your way- it’s cool.
  7. Find that margarita, mojito, or magical 4oz of white wine and have your own fiesta!
