Preheat oven to 350° and spray a pie plate with non-stick spray
Pat hash browns onto bottom of pie plate to form a base in lieu of a pastry crust.
Add vegetables of choice on top of potatoes. Cooked leftovers, frozen, or softer varieties (spinach, summer squash, zucchini, peppers) of fresh vegetables work great.
If using harder veggies (asparagus, broccoli, cauliflower), blanch them before adding to quiche by boiling a pan of water and placing the vegetables into the boiling water for 2-3 minutes. Remove with a slotted spoon, chop, and add to quiche.
Crack your eggs into a bowl and add spices and milk. Beat with a hand beater until thoroughly combined. Pour over veggies in pie plate.
Top with cheese. Bake for 40 minutes at 350°
Allow to cool for 5 minutes before cutting into perfect triangles to serve.
