Preparation Techniques for Tilapia Filets
I've found two good things to do with this fish (I dislike it broiled/baked): fish curry or soup, and fish tacos. I find the fish too bland to really do much on its own, but it serves as a decent base to the different pepper sauces that i put on tacos.

For curries, the Indian state of Goa has some good ideas on what to do with fish, as do the Thais. You can find many recipes in different books and the internet. Talapia will generally sub in for whatever whitefish they call for, although it has a bit less flavor than most.

My personal favorite fish soup is the Hungarian halászlé. I don't have a good recipe--I usually make it up as I go along--but google should find you some.
