Preheat oven to 375 degrees. Prick the bottom of the pie crust with a fork. Bake for 5 minutes. Set aside.

Meanwhile, in a nonstick pan melt butter. Add onion, red bell pepper, and green bell pepper. Cook until soft, about 5 minutes. Let cool slightly.

In a medium bowl, whisk together eggs and half-and-half.

Add salt, pepper, garlic powder, ham, onion mixture, and cheese. Stir to mix. Pour into pie crust.

Place pie crust on a baking sheet and place in oven. Bake 40 to 45 minutes. Serve warm or cold.
