First things first: What you see at your grocery store is almost certainly NOT a yam. It’s a sweet potato.
Why are sweet potatoes so great?
They are simple to cook. You don’t even have to peel them.
You can make a lot of dishes from them—from soup to fries.
They store (raw or cooked) for several days in the refrigerator.
This easy-to-add vegetable is also a good helper for those of us craving a little something sweet after lunch. They aren’t candy, but they might be sweet enough to save you from other workplace temptations.
