Toppings of your choice
Slice sweet potato into pieces which will fit into a toaster. (Don't make them too thick)
Pop the sweet potato in the toaster, and when it pops up, check how hard it is. Repeat until the sweet potato is soft to stab with a fork.
Top with anything you like. (Sweet or savoury.)
Peanut Butter. (I was hugely skeptical about this one but it's actually really good.)
