Stuffed Chard Leaves

1 onion, chopped
1 tbsp oil
2 1/2 cups cooked brown rice
1 1/2 cups cottage cheese
1 egg, beaten
1/2 cup chopped parsley
3/4 cup raisins
1 tsp dill
3/4 tsp salt
5 -10 large swiss chard leaves

Preheat oven to 350 F. Sauté onion. Mix all ingredients except chard. Wash and dry chard and remove stems. Place 2 tbsp of filling on the underside of the leaf, a third of the way from the bottom. Fold over the sides of the leaf and roll up into a square packet. Place seam-side down in a greased casserole. Cover and bake for about 30 minutes. Bake any extra filling and serve with stuffed leaves.
