Start by making the salsa: dice the 2 avocados and the mango in 1 cm cubes, the onion and tomatoes into 0.5 cm cubes and mix it all together. Add lime juice and the cilantro roughly chopped. Salt to taste, mix well and set aside.
Warm the tortillas in a pan for 1-2 minutes, but make sure they don't dry out!
Break the fish filets into pieces. Carefully check out for bones - the last thing you want is breakdance with your tongue to locate a tiny bone in a mouthful of goodness. Microwave the fish for 30 seconds.
When the tortilla is ready, put two spoons of salsa on it, a few fish pieces, and squeeze out some hot sauce on it (ok, a lot!).
