|Roasted Japanese and Jewel sweet potatoes.|
I just cooked two varieties of sweet potatoes—Japanese (the whitish) and Jewel (orange)—and it took just a couple minutes of active preparation. The payoff in flavor and nutrition, though, far exceeds the effort.
After washing the sweet potatoes, I cut them into smaller pieces and put them into the toaster oven (375 degrees). About 25 minutes later, they were soft. After they cool, I'll store them in the refrigerator and eat over the next several days.
Remember, cooking does not have to be a Julia Childesque production.
