Here is my go to Quiche, Thud

Crustless Quiche
Dozen large or jumbo eggs
2 cups heavy cream
2 cups shredded cheese (cheddar, swiss, mozzarella, monterey jack etc)
1 to 2 cups of cooked meat (bacon, sausage, spam, ham etc)
chopped onion to taste (optional) - (remember the carbs!)
broccoli or other cooked veggie or fresh baby spinach (optional)

Whip up the eggs and cream. Fold in other ingredients. Pour in a 9x13 inch pan (or a large cast iron skillet). Or do what I do and pour in a large muffin pan (makes 12 muffins). Either way use cooking spray first or butter the pan. Bake 20 minutes at 350 degrees or until cooked through (a little longer if in the 9x13 pan). This freezes exceptionally well, just nuke in microwave for 60 seconds or so. Make a batch on the weekend for quick and easy breakfast during the week.

Bake at 350 for 35 minutes.. let cool before cutting.
(Leftover taco meat is great for Mexican flavor)
