Taco Quiche

I made this quiche for a girl's night at a friend's house.  Because of needing to be grain free, I modified two recipes to make this one.  It came out pretty well. Next time I might add a salsa layer to the top.  One of the recipes called for chopped lettuce as a topping which might be a nice addition as well.

1 lb. ground beef
1 packet taco seasoning
1/2 cup chopped onions
6 or 7 eggs
1/2 cup sour cream
3-4 cups shredded cheddar cheese (I shredded about 16 oz of cheddar cheese)

Toppings:
3/4 cup chopped tomato
1/4 cup chopped green pepper
1/4 cup chopped green onions
2 cups shredded mexican blend cheese
1/4 cup of olives.

Preheat oven to 375. Grease casserole dish.  Brown ground beef with onions.  Drain. Add taco seasoning. Prepare according to package directions.

In a large bowl beat the eggs well.  Add sour cream, beat well.  Stir in taco seasoned meat and cheese. Bake uncovered for 30 minutes.  Cool for 10 minutes.  Spread sour cream over the top.  Sprinkle with tomato, onion, green pepper, olives and cheese.  Serve immediately.
