Over medium high heat, cook pepper and onions in the olive oil for about 5 minutes or until soft.
Add the sausage and cook, breaking up until no longer pink. Drain off excess grease.
Whisk together eggs, cream, and seasonings in a large bowl.
Fold sausage, vegetables, and cheese into egg mixture. Pour into a prepared quiche dish and bake 35 minutes or until set in the middle. Let cool 5 minutes before cutting.
Notes
Ham or cooked and crumbled bacon can be substituted for the sausage and added to the mixture last.
You may substitute a different cheese if you prefer, such as cheddar or Monterey Jack.
