Matthew's Avocado & Salsa Burger

Pat out burgers made of one pound lean ground beef or sirloin. We use grass fed beef. Toast onion rolls or your favorite buns with a little butter or olive oil on them. Melt some mozzarella cheese on you burgers after they cook. Top with sliced avocado and salsa. Matthew makes his own salsa with onions. Serve with a side salad. It's an awesome twenty minute meal!
