"Spanish Sauce"

#fbf : My grandma used to make this for me, and now I make it for myself. She always called it "Spanish Sauce," although I don't know that it's an authentic Spanish recipe. It generally starts with olive oil and onions, and always includes tomatoes and green bell peppers, with tomato sauce. Everything is cooked together until you feel it's "done." Grandma used to serve this sauce with eggs or over rice. It's very simple to make, and very delicious!
