Preheat oven to 375 degrees F.
In a skillet over medium-high heat saute the bell peppers and onions until softened. Set aside.
In the same skillet brown the ground chorizo until it is cooked through. Drain excess grease and set aside.
In a bowl add eggs and 1 cup of heavy cream. Whisk together.
Spoon the sausage, bell peppers, onion, and green chilies into a greased 11x7 inch casserole dish.
Sprinkle the shredded cheddar cheese over everything.
Pour the egg mixture over the meat, vegetables, and cheese, and use a spoon to move things around just a bit to let the eggs get down into the mixture.
Place in the oven and bake for 35-40 minutes or until you can jiggle the pan and the quiche doesn’t shake in the center.
Remove and let cool for about 5 minutes before cutting and serving.
