Add the olive oil to a regular, heavy-bottomed pan. Add all chopped ingredients, sauteing for 1-2 minutes. Then add filets into the pan with the vegetables and squeeze lemon or lime over everything. Cover with saucepan with lid. Cook on medium for about 10-12 minutes. Uncover the pan, and use a spatula or fork to break apart the fish into bite-size peices. Let simmer a few more minutes, add salt and pepper to taste. Heat tortillas and spoon mixture onto tortillas, using a slotted spoon or spatula to allow extra juice to stay in pan. Roll up tortillas and enjoy!Fish Fajitas a la Santa Barbara
