Preheat the oven to 350 degrees. Line the crust with parchment paper, fill with pie weights (or beans, rice, etc. - something heavy), and bake the crust for 20 minutes. Once the pie crust is done, remove it and set it aside to cool.
Heat a skillet over medium high heat and add the diced Andouille sausage. Cook until browned on all sides. Remove the sausage from the heat and set it aside.
Whisk together the eggs, cream, milk and seasoning in a bowl and set aside.
Sprinkle the cheese in the bottom of the pie crust and add the shrimp pieces, cooked sausage, onions and green peppers on top.
Pour the egg mixture over the top. Bake for 45 minutes, or until fully set.
Remove from the oven and let cool. Slice and service it slightly warmed.
Any kind of smoked sausagecan be substituted for the Andouille sausage.
Cheddar cheese has the best flavor for this recipe, but any melt-able cheese can be substituted.
Jiggle the quiche slightly to determine whether it is done. If it still jiggles, place it back in the oven for 3-5 minutes until fully set.
If the crust starts to brown too much, wrap it loosely in foil to prevent it from burning.
