Thanks RedHare and Torn.
I ended up making up my own recipe based on those I found online- pretty similar to RH's.
Sprayed saucepan with Pam (real authentic, I know), threw in half a diced onion, half a diced green pepper, a few crushed cloves of garlic, and a few sliced cloves of garlic. After that was soft, I added 4 diced tomatoes, a diced roasted red pepper, some salt and crushed red pepper. Brought to a boil, let simmer for a while.
It was

, but I'll probably play around with the recipe a little for next time.
