Quiche!
This is what I did for tonight's quiches. (Borrowing from these recipes: 1 2 3) It could stand some modification, though.
3 medium-small onions, chopped
1 lb mushrooms, chopped
2 10oz pkgs frozen leaf spinach, defrosted
Sauteed onions a bit in a butter-canola oil mixture, then added mushrooms. Added salt, pepper, a bit of thyme and a bit of nutmeg. Continued sauteeing for undefined period of time, then turned the heat off and added spinach. Stirred.
Grated 8 oz of swiss cheese. Put about 3 oz each in the bottom of 2 premade, defrosted frozen pie shells.
Made a mixture of 6 eggs, 2 cups of milk, 2 TBS flour, 1/2 tsp powdered mustard, 1/2 tsp salt, a good shake of paprika and a good shake of nutmeg.
Divided most of veggie mixture between the two pie shells. There was still a lot left. Sprinkled remaining 2 oz of cheeze on top of veggies. Poured egg-milk mixture into each pie shell. There was a lot left.
Baked @ 375° for about 40 minutes. Dumped remaining veggies and egg mixture into a greased 8x8 pyrex, sprinkled cheddar cheese on top, baked at temps varying from 375° to 400° for an undetermined amount of time.
To change:
*use chopped spinach. whole spinach doesn't mix well and is kind of clunky.
*possibly chop mushrooms and onions in smaller pieces.
*mix everything together before dumping into pie shells, since the veggies and the milk-egg-cheese didn't get entirely evenly dispersed.
*scale down the amount of veggies and egg mixture, or use more cheese and make three quiches instead of two
*do not sprinkle cheese on top. cheese puffs up and browns, making it hard to see if the egg mixture is set/cooked.
