Mushroom Gruyere Tart

Ingredients:

1/2 onion, sliced
8 oz. baby belle mushrooms, sliced
1 1/2 c. Gruyere cheese, shredded
1 tsp. garlic salt
1/2 tsp. fresh cracked black pepper
2 Tbs. butter
1 pie crust (I used Pillsbury)

Preheat the oven to 375 degrees. Press the pie crust into the bottom of a quiche pan. In a large saute pan, heat the butter on medium heat. Add the onions and cook for 5 minutes, stirring occasionally. When the onions are translucent, add the sliced mushrooms, garlic salt and fresh pepper. Stir until the mushrooms are soft. Pour the filling into the pie crust. Top with the Gruyere cheese evenly. Fold the edges of the pie crust over on top of the filling slightly. Bake for 25-27 minutes until the cheese is golden brown. Let cool slightly before serving.
