Caramelize a ton of onions, make some mashed potatoes. I suppose you could use instant potatoes if you really want a simple hack. Par-cook lasagna noodles, then put multiples layers of the noodles, potatoes, onions, and of course some kind of simple cheese in a casserole dish as you would with lasagna. You could get fancy and add some fresh herbs. Top with the cheese to get that awesome bubbly, crunchiness that comes with a good lasagna. Bake 20-30 min, serve with a horseradish sauce or sour cream, or just dig in straight up.
