Preheat oven to 400 degrees.

In a large piece of foil, place your fish fillets and cover completely with salsa. Sprinkle with salt and pepper (if you are doing the 21 Day Fix, skip the salt)

Fold foil over the fish to make a sealed container.

Grill over medium heat on your grill for 6-8 minutes, depending on the thickness of your fish.

Meanwhile, lay your tortillas flat on a cookie sheet and bake in the preheated oven until completely crisp, but not brown, about 6-8 minutes.

When finished, let cool a minute and then spread with mashed avocado or guacamole (if doing the 21 Day Fix, use only the amount that fits in your blue container.)

When fish is ready, flake apart with two forks and then spread on top of guacamole. Top with salsa from the foil packet and then garnish with any desired toppings, enjoy!
