A frittata is a flat omelet with a medley of vegetables and herbs mixed into it. This recipe calls for zucchini and chard, but you can substitute any summer squash for zucchini, and spinach for the chard.
Good served hot with stew. Note: if you don't have buttermilk or sour milk you can make some for this recipe by putting lemon juice (or vinegar but I like lemon juice better) into a measuring cup and then pour in milk to make 1 1/4 cup. Let set for 10 minutes at room temperature before using.
