Dice the tomatoes, peppers and onions and place on a cookie sheet. Break up the pork sausage into pieces and put all over the pan. Turn the oven to broil and place the cookie sheet in and bake for 7-10 minutes. Watch the tops of the veggies and meat carefully so they don't get too burned. If you need to toss the mixture so all sides of the pork get cooked, you can. Once the sausage is cooked and the veggies are nice and browned, it's ready.
In a large blender, pour half of the mixture and blend until smooth. To the blender, add 1 or 2 of the tomato sauce cans to the sauce and blend some more. Pour this mixture in a bowl if ready to serve immediately, or pour into a pot to continue simmering until ready to serve. Do this same technique with the second half of the veggies and sausage and blend until smooth. Add the last can of tomato sauce and get ready to serve.
Cook the noodles until tender and serve the sauce over your favorite pasta, zoodles, etc.
