Preheat the broiler. Place filets on a foil lined baking sheet. Season with salt, lemon pepper and a squeeze of lemon on each filet and broil for about 12 minutes, or until the thickest parts flake easily.
In a medium sized mixing bowl, mix up the green onions, avocados, mangoes, jalapeños, cilantro, cumin and salt & pepper. Set aside.
Heat up a frying pan (I like to use our crepe pan) and spray with cooking spray. Place tortillas on pan and heat each tortilla until warmed up.
When the fish is done, shred it up with a fork and place in a row down the middle of the tortillas and top with mango salsa. Serve immediately and enjoy!
