So Simple Ideas
Preheat oven to 350°F. Add the onions to the hot skillet with olive oil and sauté for a few minutes until beginning to soften. Add the spinach to the skillet and sauté until wilted. Let cool.
Whisk together the eggs, heavy whipping cream, garlic powder, and salt and pepper to taste in a bowl until well combined.
Place a bit of the onion and spinach mixture in the bottom of 8 sections of a well greased muffin tin.
Fill the sections of the tin ⅔ of the way full with the egg mix. Sprinkle some cheese and bacon on top of each of the cups.
Bake for 20-25 mintues until cooked throughout.
