This rich and cheesy quiche is perfect for using up leftover ham.
Preheat oven to 375 degrees.
Melt butter in a small nonstick pan and cook onion until soft. Let cool slightly.
In a large bowl, whisk together eggs, half-and-half, salt and pepper.
Stir in ham and both cheeses. (I like to leave a small handful of cheese to sprinkle on top.)
Stir in cooked onion.
Pour filling into pie crust, set on a baking sheet and place in oven for 40 to 45 minutes, or until set.
Serve warm or chilled.
