Generously oil a cookie sheet or 11x13 pan. Wash and cut 3 pounds of non-Russet potatoes (I threw in some sweet potatoes, because I buy them compulsively.) into chunks that are coincidentally about half the size of a baby potato. Dump into the pan. Cut one large onion into 1/4 inch thick slices and dump on top of the potatoes. Sprinkle with 1 tsp. salt and 1 tsp. sugar.
Bake in a 400 degree oven for about an hour, or until the potatoes are tender and the onions are really really tasty. Eat.
