It's my favorite! We don't follow the exact same recipe each time (sorry Kara). We start by sauteing onions in olive oil (and sometimes green pepper too). After that is ready, we add the tomatoes to it - this part varies depends on what is in the pantry - about 2 cans of diced tomatoes (Del Monte is our favorite!) and 1 can of tomato sauce. Then we add spices - salt, pepper, basil, a green serano chilli, maybe a bouillon cube... Bring to a boil and then cover and let simmer. On this occasion we had some cheddar cheese to use up, so we grated it up on top in place of parmesan.
