Cook sausage in a large skillet over Medium heat until fat begins to render

Once fat is rendered, push to one side, and add diced onion

Cook onion for 2-3 minutes, until onions begin to "sweat"

Next, add tomatoes and incorporate with sausage and onion; cook for 2-3 minutes

Add mixed greens on top until they begin to wilt, and then mix in with previous ingredients
