Crustless Spinach Quiche

Ingredients 
1 tablespoon olive oil
1 medium onion (finely chopped)
2 cloves garlic (minced)
10 ounces fresh spinach (roughly chopped)
4 large eggs
½ cup milk
1½ cups Gruyere cheese (shredded)
½ cup feta cheese (crumbled)
½ cup Pamesan cheese (grated)
salt and pepper (to taste)
1 pinch nutmeg

Preparation

1. Preheat your oven to 375°F. Generously spray a 9-inch pie dish with cooking spray.
2. Heat the olive oil in a skillet over medium heat, and cook the onion and garlic until they’re soft, just a couple of minutes. Add the spinach to the skillet and cook until wilted, which should take about 3-4 minutes.
3. In a mixing bowl, beat together eggs and milk. Stir in the Gruyère, feta, and Parmesan cheeses, along with a pinch of nutmeg. Season with salt and pepper, and whisk it all together.
4. Spread your spinach mixture in the prepared pie dish. Pour the egg and cheese mixture over the spinach. Give it a gentle stir in the dish to make sure the ingredients are evenly distributed.
5. Pop your dish into the preheated oven and bake for 30-35 minutes, or until the quiche is set and the top is golden brown.
6. Let it cool for a few minutes before slicing. This helps everything set nicely.
