We actually do these at the "Halfway House" out on the golf course at work. They keep some sausage patties, bacon, and sliced ham available for the breakfast-minded early golfers.
Tip on speed: Get a large griddle, or 12" skillet. Butter the cut sides of the muffin while the skillet heats. Once it's hot, lay the muffin down, crack the egg into the buttered/greased egg ring, and put down the meat. Flip the meat when ready, remove the muffin when it's toasted, and remove the egg ring when the egg is almost set, then flip the egg to finish cooking. I put cheese on the egg when it flips (usually American cheese, it melts faster). Assemble and eat. I can get one made in about 5 minutes.
Try making some Tennessee Mountain bacon. Lay some bacon on a sheet pan, sprinkle with brown sugar and black pepper. Bake until it's done, but not burnt.
