All you do for my yummy spaghetti is add the following to your already prepared noodles and sauce.
Olive Oil (or Vegetable Oil)
1 Red Bell Pepper, sliced into strips
1 Green Bell Pepper, sliced into strips
1 Yellow Bell Pepper, sliced into strips
1 Orange Bell Pepper, sliced into strips
1/2-1 onion sliced into strips (depends on how onion you want it)
1-2 garlic cloves minced (depends on how garlicky you want it)
1 pound Mild or Hot Italian Sausage
Preheat oven to 350. Get a cookie sheet with the high edges (not the ones with no lip on the edge). Poor a good amount of oil into the pan and place sausage on it. Rub each piece of sausage with oil, covering it. Cook in oven 20 minutes on each side (40 minutes total). When they are done slice into little circles.
Heat about 2 tablespoons olive oil in a pan on medium heat. Add Garlic and sautée for about five minutes. Add Onion and Bell Pepper. Sautee for about 20 minutes, or until veggies are to desired consistency. Add sausage and about a cup full of sauce to deglaze the pan (mix sauce in and then rub the pan bottom to get all the nice juices up off it). Serve on top of spaghetti.
