Assemble the ingredients. Clean and chop the vegetables. (1/4 cup red bell pepper, 1/4 cup green bell pepper, 2 teaspoons jalapeno, 1 Tablespoon red onion). Set the pie crust out of refrigerator for about 15-20 minutes.
Brown 1/2 lb sausage, drain grease. Stir in the 4 oz can of diced chiles. Set pan aside to cool slightly.
Preheat oven to 350 degrees F.
Unroll the pie crust and press onto the bottom and up the sides of an ungreased 9″ tart pan with a removable bottom. Prick crust on bottom and on sides in about 8-10 places, with a fork.
Sprinkle 1/2 cup of cheese in the bottom of crust.
Evenly spread the sausage in the pan. Top with the green and red bell peppers, jalapenos, and red onions. Add 1/2 cup cheese over the ingredients. Place the pan on a parchment lined baking sheet.
In a medium size mixing bowl, using an electric mixer, combine the 6 eggs, 1/3 cup half-and-half, and salt and pepper. Pour over the sausage. Sprinkle top with 1/2 cup cheese.
Bake for 28-30 minutes, until eggs are set. Lightly shake the pan to check this.
Remove from oven to a cooling rack for 15-20 minutes, then remove sides of pan. Allow to cool another 15 minutes, then run a long sharp knife under the bottom of tart to remove bottom of pan.
Transfer to a serving platter. Arrange toppings with the tart.
