In a large skillet over medium heat, melt butter then add onions or mushrooms. Saute onions approximately 20-25 minutes or until golden brown. Mushrooms caramelize in about 10-15 minutes. These can be seasoned with salt once cooked. Remove from skillet, set aside and keep warm.

Place patties in same skillet and brown, approximately 5 minutes per side. (Tip: Do not move the patties for a few minutes. Do not press down because this squeezes the juices out and makes them dry. When they are browned on one side, flip them over and brown the opposite side. Don't worry about cooking through.).
