They’re awesome for pasta sauce. I sautee a diced onion and tomato paste in olive oil, add a ton of chopped garlic, and then a couple large cans of tomatoes (or peeled whole tomatoes if available). Add 1/4-1/2 cup of red wine, some salt, perhaps mushrooms and herbs, and simmer for 20 minutes and then put in the oven at about 360 for 2-2.5 hours. It takes way less stirring then on the stovetop and comes out very nicely reduced and flavorful.
