FOUND IY: Laura tore it out of a copy of Shape magazine.
MODIFIED IT: Only to increase the seasonings
I eat sweet potatoes in several ways, but when I make them at home, this is how I do it.
Two medium-large sweet potatoes
1 tbsp (or so) olive oil
1 tbsp garlic powder
1 tsp cinnamon
1 tsp cumin
Salt and pepper to taste
Peel sweet potatoes and chop them into 1/2-3/4 inch cubes. Toss them in the oil, garlic, cinnamon, cumin, salt and pepper. Spread them in a single layer in a baking dish, and bake in a 425 oven for 45 minutes, stirring once around halfway. They'll be tender when they're done.
