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.

I tend to treat tilapia similar to chicken in that it's kind of a blank canvas onto which you project other flavors.
It doesn't work everywhere chicken does, but one of my favorite uses is to chop it into little bits, and "stir fry" it.
I season those browned bits and use them as the base of actual stir fry or with Mexican seasonings in tacos, etc.

I know fish and cheese is supposed to be a sin.
Luckily, I'm not one to play by the rules most of the time, I go by what I enjoy :)
My wife is very picky, especially about fish, so if I want her to eat it, I have to mask it sometimes...at least at first to warm her up to the idea of something new.
When I first wanted her to try tilapia
I made this: Parmesan-Herb Baked Flounder but subbed in tilapia.
She loved it, and since then, I've been able to convince her to try (and enjoy!)
tilapia with simple marinades, broiled or on the grill.
But this recipe was a stepping stone.
Even now, I still make this on occasion, and I make 10 filets at a time -
and they last about 2 days max in our house.

It's quite delicious simply sautéed/seared with salt and pepper.
The real fun is serving it with perfectly glazed carrots and using that glaze as sauce for the fish, as well!
You must try this.
The sweet and buttery glaze make the slightly salty fish divine!
I eat this about once a week and can't get enough!

I do this with Salmon, never tried it with Tilapia
but I imagine it would still taste great!
I basically take the salmon fillets and sprinkle garlic powder, ground black pepper, and cayenne pepper.
Then I brush each of the fillets with 1 tbsp of olive oil.
If you don't like the fishy smell, squeeze a few lemons over it and/or cut up a few slices of lemon and lay it over each of the fillets.
Then I pop it in the oven @ 375 degrees and bake until the fish is cooked or until flakey (depends on the size of your fillets).

In my freezer, I have two thin tilapia filets that need to be eaten.  I realize that I can:   wrap them in foil with seasoning and cook  bake or broil them with butter, wine, lemon juice, and/or other seasonings  bread and fry them  grill them    What I'd love to know is what I'm missing: what's are techniques to use with this mild-flavored fish in it's preparation?

Some enjoy it simply sautéed/seared with salt and pepper, but others find it quite bland and prefer it as a base for stronger flavours. You can use it to make fish tacos, curry, parmesan/herb baked fish, or treat it like chicken breasts in stir fries or similar dishes. Use it in flavourful dishes like curry and tacos or simply fry in salt and pepper.
The flavour is quite bland, so you should use it in flavourful dishes like curry and tacos. You can also bake it with cheese. You can simply fry it with salt and pepper. You can cook it like you would chicken, which is equally bland. A stir fry would be a good idea.
