Preheat oven to 375°F (190°C). Grease two 9-inch pie dishes.

Cook sausage: Slice sausage links into bite-size pieces and cook in a skillet until browned. Set aside.

Prepare filling: In a bowl, beat 10 eggs with salt and pepper. Stir in vegetables, cooked sausage, and shredded cheese.

Assemble pies: Line each dish with bottom pastry crust. Pour filling evenly between the two. Cover with top crusts, sealing edges and cutting small slits for steam.

Egg wash: Beat the remaining 2 eggs and brush over the tops for a golden finish.

Bake: Place pies on a baking sheet and bake 40–45 minutes, until crusts are golden and centers are set.

Rest & serve: Let stand 10 minutes before slicing.
