Swiss Cheese & Mushroom Quiche

I'm not sure where I found this recipe- I've had it for years. It's truly amazing!

• Ready In: 1 hr 5 mins
• Yields: 1 pie

Ingredients

• 1  pie crust (Homemade is ALWAYS best)
• 1  teaspoon butter
• 1 1⁄2 cups  chopped onions
• 1⁄4 lb mushroom, sliced
• 1⁄2 teaspoon salt
•  pepper
• 1  pinch thyme
• 4  large eggs
• 1 1⁄2 cups milk
• 2  teaspoons Tabasco sauce
• 2  tablespoons flour
• 1 1⁄2 cups  packed grated swiss cheese

Directions

1. Preheat oven to 375.
2. Melt butter in small pan. Add onions & saute over medium heat. When they begin to soften, add mushrooms, salt, pepper & thyme. Saute 5 minutes more and remove from heat.
3. Combine eggs, milk, Tabasco, and flour in a blender or food processer.
4. Spread cheese over bottom of pie crust, and spread onion/mushroom mixture on top. Pour egg mixture over that and top with tomato slices. Sprinkle with paprika.
5. Bake for 35-45 minutes, until solid in center. Test by inserting a knife in the center. If it comes out clean, the quiche is done.
