  • In a medium mixing bowl, lightly beat eggs. Add the milk, garlic salt, and pepper and combine well.
  • Remove crust from oven. It is ready when dough in center is set, but not browned.
  • Spread sauteed vegetables over crust.
  • Pour egg mixture over vegetables.
  • Sprinkle shredded cheese over egg mixture and bake quiche in 350 F oven for 40 minutes, or until knife inserted in the center comes out wet, but clean. Cool for 10 minutes and serve.
