Spinach Cheddar Quiche

I love breakfast for dinner.  If there are enough leftovers I don't have to cook in the morning!
This recipe can take many forms. I usually add mushrooms but didn't have any around today. 
You could also substitute any number of other foods: You could use chopped broccoli instead of spinach, and add chopped ham, crumbled bacon or sausage.  Chopped peppers would also be good.  The possibilities are endless.

Spinach-Cheddar Quiche

1 Tbsp. oil
1/2 c. chopped fresh spinach
1/4 c. chopped onion
1 c. shredded cheddar cheese
2 c. milk
1 c. biscuit mix
4 eggs
1/4 tsp. salt

1.  Saute onions in oil until tender.  Add spinach and cook another 1-2 minutes until slightly wilted. 
2.  Spoon into lightly greased pie plate.  Sprinkle with cheese.
3.  Combine remaining ingredients in a blender until smooth.  Pour into pie plate
4.  Bake at 400 degrees for 30-40 min. (depending on size of pie plate)  The top will be lightly browned and the center will be set.
