Recipe: Carmelized Onion, Gruyere, and Spinach Crustless Quiche

I got this recipe out of the local newspaper that comes out once a week, which apparently got it from Food.com.  I've been looking at the picture and wanting to make it for a few months now, and Andrew and I actually made it last night.  It turned out really well and we'll definitely make it again with a few changes.  I would definitely add a crust and possibly use a different cheese so that the flavor stands out a little more because the onions kind of overpowered the rest of the flavors.

Ingredients:

• 1-2 onions, peeled and sliced
• 1 (10-ounce) box frozen spinach, thawed
• 1 cup gruyere, grated
• 4 eggs
• 1 1/2 cups milk
• nutmeg
• salt
• pepper

Directions:
Preheat oven to 375 degrees.  With a little oil in a frying pan over medium high heat, carmelize onions.  Squeeze the moisture out of the thawed spinach.  Beat eggs.  Add milk and whisk well.  Season the mixture with salt, pepper, and fresh nutmeg.  Oil a deep pie dish.  Place onions evenly over bottom of pie dish.  Evenly spread the spinach over the onions and follow up with the cheese. Pour the egg mixture over the top.  Bake until firm in the middle, about 40-45 minutes.
