Over medium high heat add 1 tbs of oil in a large skillet pan . When oil is hot add your sliced sausage nuggets. Saute until they begin to brown. Should take about 5-7 minutes. Remove the sausage from the pan, set aside and keep warm.
In the same pan, retain the oil and sausage drippings and add your sliced pepper and onions. If you need more oil go ahead and add the other tbs. While your peppers and onion are cooking add your garlic, oregano, basil, salt and pepper. Saute peppers and onion until soft. I actually like mine browned and the onions carmelized. About another 7 to 8 minutes
Once your peppers and onions are almost where you like them add the sausage back to the pan. Cook the sausage and peppers together until the sausage is cooked through and your onions are nice and carmelized. about 3-4 minutes.
