If you are making your own pie crust make the crust and then put it into the fridge until you need it. Preheat the oven to 350°F.
In a large skillet over medium-high heat, brown sausage, and after it is done cooking drain the sausage and set aside. While browning the sausage steam the broccoli.
In a large mixing bowl add the sausage, mayo, milk, pepper. broccoli, eggs, and cheese and mix well.
Using a 9-inch pie plate, roll the pie crust into your pie pan and pinch the top edges. Be sure to get the pie crust fully in the pie plate.
Pour the broccoli and sausage mixture into the pie crust., use a spatula to make the mixture evenly distributed in the pie crust.
Bake at 350 for 35- 45 minutes. Until you can poke it with a knife and it comes out clean.
Take the cooked quiche out of the oven and let cool and set for 15 minutes before serving.
