Easy Crustless Spinach Quiche

Preheat oven to 350 degrees Fahrenheit and lightly grease a 9-inch deep dish pie plate.

Heat olive oil in a large skillet over medium high heat. Add in onion and mushroom and saute until softened, about 5 to 7 minutes. Add in garlic and cook 1 minute more. Turn off heat and stir in spinach, feta, and cheddar cheese. Spoon mixture into the prepared pie plate.

In a mixing bowl, whisk together eggs, milk, salt, and pepper. Pour egg mixture over the spinach mixture in the prepared pie plate.

Bake in the preheated oven for 40 to 45 minutes, until eggs are set. Let cool 10 minutes before slicing and serving.
