Frittatas are what I usually make when I have a bunch of leftovers. For example, today I was cleaning out the fridge found a half bag of hash brown potatoes, some leftover ham and a jar of fire-roasted salsa a friend brought over on Saturday. I added a can of diced green chilies and used the salsa as a topping and had a great lunch.
You really don't even need a recipe. Just heat up about 3 cups of leftover meat and/or veggies, add 4 beaten eggs, a few spices and you're all set.
So, what kind of frittata can you make from your leftovers?
