Preheat your oven to 375° F degrees.
Wash and trim the asparagus, cut into ½ to 1 inch pieces.
In a skillet, add olive oil, minced garlic and chopped asparagus spears. Sauté the spears and garlic for about 1 minute, but no more than 2 minutes. Don’t overcook the asparagus as you don’t want it to be soggy in the baked quiche.
Take skillet off the heat and set the asparagus to the side to cool while you make the egg mixture.
In a bowl, add eggs and whisk gently. Pour in evaporated milk, salt, pepper and onion powder. The eggs are whisk gently to keep from adding too much air into the mixture.
Fold in the shredded mozzarella, white cheddar and feta cheese. Mix until just combined.
Fold in the cooled asparagus.
Pour the egg and cheese mixture into the pie crust, pouring from the center. Egg mixture should come just up to the edge of your pie crust.
Place the quiche on a baking sheet to catch any spillage.
Bake the quiche in the center of the preheated oven for 40-45 minutes. Quiche is done when the sides are set and the center is nearly set. Let cool for 10 minutes before cutting into and serving.
Top with chopped chives or green onions, if you wish before serving.
