I tried to make a quiche the other day and once I had steamed the spinach and cracked the eggs, found out that I had no milk to use. Plan B, make a quiche with greek yogurt (plain, yoplait brand). It was delicious and fluffier than quiches made with milk. Here is what is left of it!
Crack 5 eggs and mix together with 1 small plain greek yogurt
Add 1/2 cup water
Add steamed spinach (1/2 large bag)
Add 2 cups of shredded cheddar (mixed kinds work fine as well)
Mix all ingredients and place into pre-made pie shell from the grocery store
Bake for 20 minutes approx. depending on how quickly the center solidifies
Easiest breakfast, brunch or "breakfast for dinner" around and super healthy too!
