The original recipe didn't have the onion or meat. I add those, but I usually don't measure, so feel free to use as much as you like. I haven't tried it, but you probably could use those prepackaged shredded potatoes you can get nowdays.
Notes from the Test Kitchen:
We used bacon as our meat of choice in this recipe and it made for a wonderfully complete meal! All the yummy flavors of a traditional breakfast in one easy dish... woohoo!
sharp cheese, grated
salt and pepper to taste
finely diced onion
cooked diced ham, browned sausage or cooked and drained bacon pieces
