This casserole is like an all-in-one brunch: a combo of potatoes, eggs, spinach, and salami. The recipe below is easy to at least partially prepare in advance so that you can pop it in the oven just before you decide it's time to eat.
If you're not a fan of fried eggs, you can also whisk the eggs together before pouring them over the casserole. You'll end up with something closer to a frittata, but it'll be just as delicious.
