Ask my wife for the recipe and she said ahhhhhhh.......she makes a lot of stuff she just puts together and it may not be the same the next time she does it.
But here is at least a general idea of what went into making it.
Diced boneless bluegill fillets uncooked
Lemon juice - enough to cover and coat the fish well. Doesn't have to completely float the fish, just make sure it all gets covered good.
Mix those two together then start adding other ingredients. Only takes a few minutes for the lemon juice to "cook" the fish. (note: larger fillets would take longer to "cook" in the lemon juice. The fish flesh should go from translucent to white just like it would if being cooked with heat)
Diced fresh tomatoes
Diced onions
cilantro
Diced green or red bell pepper, a little jalapeno pepper if a person wants it a little spicy
Salt to taste. Can add black pepper if wanted
That is it. Sounds pretty quick and easy. Easy for me that is as the wife does it. She makes it and I eat it.......the perfect combination.
