1 can crushed tomatoes
1 can tomato sauce
1 medium onion, diced
1 small bell pepper, diced
4 cloves garlic, minced
Heat the olive oil in a sauce pan, then saute the onions and bell pepper until the onions start to go translucent around the edges.
Add the garlic and saute until the garlic is fragrant and has just a little bit of golden brown color.
Add the cans of tomato, bring to a boil, then turn onto low and simmer for as long as you can. Be careful, as tomato sauce pops and splatters a lot if it boils too rapidly, so only let it come to a gentle boil, then cover with a lid as it simmers. The longer you are able to let it simmer, the more flavorful it will be.
