Preheat your over to 400F.

Slice your onions and peppers and set aside.

In pan, brown your sausages on all sides, then remove to an overnsafe dish and continue to cook in the oven.

Rotate your sausages as needed.

While your sausages are cooking, throw your onions and peppers in the same pan you browned the sausages in and cook until the onions begin to caramelize and the peppers soften.

Add the Italian seasoning, and caramelize a little more.

Add the wine or vermouth. This also served to deglaze your plan and adds lots of yummies to your peppers & onions. Yummies is a technical term.

Toss this mixture over your sausages, return to the oven if need be, but your dish is probably ready to eat at this point.
