Ham and Cheese Frittata

This post should be subtitled: I was too exhausted to cook dinner because I spent the day at the pumpkin patch with 100 kindergarteners.  Wow, I don't know how teachers do it every day.  They certainly don't make enough for what they do!  

Ham and Cheese Frittata (serves 2)

1/2 Vidalia onion, chopped
1/2 cup-1 cup chopped leftover ham
6 eggs (I use 3 whites and 3 whole eggs)
splash of skim milk
2 slices cheddar cheese
1/4 cup Parmesan cheese
2 tablespoons chopped fresh basil

Preheat broiler to high.  Saute onion in a drizzle of olive oil in a non stick pan until lightly browned.  Add ham and stir until ham is heated through, less than a minute.  Add eggs beaten with skim milk and stir for about a minute.  Let the frittata cook for about 3-4 minutes, or until eggs begin to set.  Add the cheddar cheese to the top, then put the entire pan under the broiler until browned and fluffy.   Add the chopped basil and Parmesan cheese and cut into wedges to serve.
