In a large bowl, using a fork or your hands, mix together pork, beef, sage, garlic powder, salt and pepper. Form into 6 flat patties about 1/2-inch thick. (Make patties as uniform and round as possible so they will be easily fit onto English muffin when broiled.) Turn on broiler to high; broil 3 to 4-inches from heat (no closer or spattering grease will throw sparks!) for 4-5 minutes until internal temperature reaches 160-degrees (165-degrees for ground chicken). Set aside.
Spray 8-ounce ramekin with cooking spray, add 1 egg and 1 tablespoon water. Microwave egg on HIGH power for 30 seconds; stir. Microwave for 15 to 30 seconds longer until almost set. Repeat with remaining 5 eggs.
Toast all English halves.
To assemble sandwiches, place 1 sausage patty on bottom English muffin half; top with egg, 1/4 cup (1 ounce) shredded cheese and top muffin half. Serve immediately or see below to freeze.
TO FREEZE: Separate the sandwich between sausage and egg. Wrap bottom muffin half with sausage in plastic wrap or parchment paper; wrap top muffin with egg and cheese. Place two sandwich halves in plastic zip-top bag and refrigerate until cool, then freeze. (This step helps eliminate freezer burn!)
TO WARM FROM FROZEN: Remove two halves of sandwich from all wrapping and place two halves beside (not on top of) each other on a plate. Microwave on 60% power for 2 minutes; flip sandwich halves and microwave on 70% power for about 30 seconds until hot.
