Preheat your griddle to 375-400 degrees and put down a small amount of oil.
Place down your veggies, add salt & pepper and toss it all together with two spatulas. Spread them out thin and let them cook for a minute or two.
Place your sausage patties down and cook for 3 to 4 minutes. Flip them to a new spot on the griddle and move your peppers and onions to cook in the sausage drippings.
Pour the red wine vinegar and sugar on the peppers and onions. Turn off those burners and toss everything together to make a sauce.
Place cheese on top of your suasage patties. Then butter your bread and put it on the griddle to toast up.
Place your sausage, peppers and onions on top of the bread while you wait for it to toast up. Once all your bread is toasted, place the top piece on and enjoy!
