Middle Eastern Rice and Lentils

1/2 medium onion, chopped
1 T olive oil
1 cup brown rice
1 T tomato paste
2 1/2 cups water
1/4 t cinnamon
1/4 cup lentils
1 t salt
1/2 cup raisins
1/2 cup chopped walnuts, slivered almonds, or pine nuts

In a large saucepan, sautee the onion in the oil until soft. Add the rice and cook and stir for a few minutes until it is toasted. Add the water, tomato paste, cinnamon, and lentils. Bring to a boil, then turn down the heat, cover, and simmer for 30 minutes. Meanwhile, preheat oven to 350 degrees. Stir the salt, raisins, and nuts into the rice. It should still be a little watery, add 1/4 cup water if it's dry. Place in a greased 9x13 pan, cover with foil, and bake for another 20-30 minutes. Serve with a salad.
