Garnet yams, peeled and sliced into 1/2 inch rounds
Preheat oven to 425°F.
Brush yam slices liberally with olive oil and arrange on a foil-lined baking sheet. Roast for 20 minutes or until golden brown on the bottom, then turn slices and roast for 15 minutes more or until both sides are nicely browned.
Let cool, then refrigerate until you want them. You can reheat them for breakfast or sneak them straight out of the refrigerator when you think no one is watching.
