The main component of this recipe, the eggs, comes in at under a dollar (though if you choose cage-free and/or organic eggs, you’ll pay more). The other major costs in this meal are the yogurt, which costs a dollar and a quarter, and the potatoes. The frittata comes together in under an hour, and most of that time hands-off. You don’t need a salad alongside (the greens are in the frittata); then again, salad never hurts. Use It UpYou’ll only use one cup of Greek yogurt for this recipe, so you’ll have extra to make smoothies in the morning.
