Sweet Potato Souffles
Sometimes even red-skinned sweet potatoes aren't necessarily orange inside; you can scrape the skin to check.
Instead of microwaving, feel free to roast them in the oven at 375 degrees F (190 degrees C).
I kept these very plain, so as not to distract you, but you can add all sorts of things - cheese, bacon, or herbs, etc. These will also shine as a dessert. Just add some warm spices and maple syrup or brown sugar to the mashed potatoes.
