Although the original recipe did not call for garlic, I like to add in about 1/2 tablespoon in when frying the veggies, but that is only optional of coarse. This makes a wonderful light dinner served with a side salad. If desired you can even throw in just a little cubed cooked ham or cooked bacon, but not too much as there won't be enough room for the frittata to fit into the pan. This is very good, and a great way to use up any leftover spaghetti or linguine pasta.
