4 cloves garlic
28 oz crushed tomatoes
1/2 tsp salt
pepper
red pepper flakes
a Parmesan cheese rind
extra virgin olive oil
Saute garlic with a large glug of olive oil.
Add crusted tomatoes, salt, and pepper and red pepper to taste. (This might be 1/8 tsp of pepper, and a pinch of red pepper flake.) Toss in the Parmesan rind.
Simmer for at least 30 minutes, stirring occasionally.
This can probably be doubled, but would require more time to simmer.
