1 lb. Tilapia filets
1-2 cups tomato sauce (your favorite jarred sauce is fine -- I used Emeril's "Kicked Up Tomato")
Preheat oven to 350.
Spray bottom of a small pan with Pam or non-stick spray (an 8"x8" or so sized pan -- you want the filets to almost cover the bottom of the pan with no space around them)
Pour sauce over the filets -- as much as you like.
Bake for 20-30 minutes until tilapia is flakey and done.
