Ham, Potato And Cheddar Quiche

9-inch pie crust
1 cup potato, boiled, peeled and diced
1 cup cooked ham, diced
2 teaspoons oil
4 eggs beaten
1/2 cup half-and-half
1 teaspoon garlic powder
1 teaspoon onion powder
salt and pepper to taste
1 – 1/4 cup shredded Cheddar cheese

Preheat oven to 400 degrees. Pierce the sides and bottom of pie crust with a fork. Bake crust for 5 minutes. Remove from oven and set aside. In a large skillet over medium-high heat, cook potato and ham in oil for 5 to 10 minutes, until golden. Remove from heat and let cool. Transfer potato mixture to pie crust. In a bowl, whisk together eggs, half-and-half and seasonings. Pour egg mixture over potato mixture in crust. Sprinkle with cheese. Bake, uncovered, at 350 degrees for 45-50 minutes. If edges of crust brown too quickly, cover with strips of aluminum foil. Cut into wedges.
