You will need a large pot which can go in the oven. I use a 3-quart. Dutch oven.
Remove casing and brown sausage if you do not use bulk. Remove from the pot put on paper towel and paper plate to drain. Leave drippings from the sausage in the pot. I also use a little olive oil to get the sausage started so it does not stick to the bottom of the pot.
Next add onions and a little more olive oil if needed and sauté till translucent. Now add the garlic and sauté a few minutes. Then add the seasonings and all the rest of the vegetables and sauté them for about 8-10 minutes.
Return the sausage to the pot. Add all tomatoes, sauce, cheeses, then mix well. Continue to heat for about 3-5 minutes on the stove and then bake 25-30 minutes at 350 in the oven.
Remove from oven stir, let rest and serve. This is a meal all by itself. You can serve this over rice with some fresh fruit, or in a bowl with some good crunchy bread for sopping up the juice.
