Pre-heat oven to 375.
In a deep-dish pie dish put your homemade or pre-made pie crust in the bottom (i use a 2 1/2 inch deep pie dish)
Wash then cut about 2 1/2 inches off of the ends of the asparagus (because that part of the stem is tough)
In a frying pan over medium heat, season veggies with salt and pepper and thyme and cook asparagus, and red bell pepper until lightly browned, about 5-7 minutes.
In a medium mixing bowl whisk eggs, milk, and 1/2 tsp salt and pepper until mixed really well.
In the bottom of the pie crust add 1 cup cheddar cheese.
Pour over whisked eggs.
Arrange sauteed asparagus and red pepper on top of the egg.
Sprinkle of couple of tablespoons of cheese on top if desired.
Bake in preheated oven for 35-40 minutes or until brown on top. If you are not using a deep-dish pie plate it may not take as long!
