My favorite chicken dishes tend to be whole chickens or chicken legs smoked or braised, but I do eat chicken breast about 1/3 of the time I eat chicken. I agree that it is basically non-vegetarian tofu, so I flavor it pretty heavily when I cook it. Usually I pound it flat and then grill at high temps. Some typical things that I do are:
Chicken paillards - pounded flat and marinaded in mustard, tarragon, garlic, balsamic, lemon juice, and olive oil - served on a mesclun salad.
Coriander Chicken - pounded flat and marinaded in coriander, cumin, pepper, ginger, garlic, lemon juice, cayenne, lemon juice, and cilantro - chopped and served on corn tortillas with a basic salsa.
I also do kebabs, marinade in 1/2 tamari, 1/4 red wine vinegar, 1/4 EVOO, and then add a lot of garlic, fresh ginger, and pepper.
