One of my favorite fast, frugal foods to prepare has always been baked potatoes. In fact, I almost continuously have them on hand, sitting in the darkness of our pantry, just waiting for an opportunity to come and be enjoyed at dinner.
There are not many foods that are as cheap as a potato. What other hearty food can be purchased in large ten and twenty pound bags for simply a few dollars? And if you are lucky and happen to have a farmer’s market nearby, you can get even better deals.
