In a fry pan, cook sausage according to directions.
While sausage is cooking, use a glass or round cookie cutter to cut out the cheese into circles approximately the same size as the english muffins, 1 for each sandwich.
Toast enough English muffins for each sausage.
After the sausage has cooked and been cooled, assemble sandwiches -- English muffin bottom, sausage, cheese round and english muffin top.
Wrap each sandwich individually with saran wrap and freeze.
When ready to eat, take out a sandwich, unwrap, place on a plate and microwave for approximately 1 minute until heated through.
