Baked Sweet Potatoes

In our house I do a lot of baking during the winter months; the reason behind this is that I don't like using the heater.The heater always gives me a headache so I try to use it minimally.So on cold days I bake something that gets the temperature up.This method works for me because we are in California,were the temperature doesn't go so low.This is one dish that I made on  a cold rainy day to keep us warm and full.
Ingredients
2 tablespoons olive oil
3 large sweet potatoes
2 pinches of dried oregano
2 pinches of salt
2 pinches of ground black pepper
Method:
Preheat oven to 350 degrees F (175 degrees C). Coat the bottom of a glass or non-stick baking dish with olive oil, just enough to coat.
Wash and peel the sweet potatoes. Cut them into medium size pieces. Place the cut sweet potatoes in the baking dish and turn them so that they are coated with the olive oil. Sprinkle moderately with oregano, and salt and pepper (to taste).
Bake in a preheated 350 degrees F (175 degrees C) oven for 60 minutes or until soft.
