Ingredients
Method
- Preheat oven to 400 degrees. Spray casserole dish with cooking spray.Crack eggs in the bowl of a stand mixer & add the flour, baking powder & salt. Using the whisk attachment, beat the eggs until very few or no lumps remain, about 10 minutes. Add the remaining ingredients - feel free to improvise here. Add chopped meats or leftover cooked veggies along with the spinach, green chilis & cheeses. Bake at 400 for 15 minutes, then cut the temp down to 350 & bake for 45 minutes or until a knife inserted in the center comes out clean & the top is set.

Notes
Without opening the door of the oven, check on the quiche every now & then to be sure the top isn't getting too browned. If you feel the top is getting too cooked, you can add a little piece of tinfoil over the top of the casserole dish to prevent further browning.
