Spanish Rice

1 C rice
1 medium onion diced
Taco, enchilada, or fahita seasoning mix (use as much to your liking, I usually use about 1-2 Tbsp)
2 small cans tomato sauce
2 cups water

Cover the bottom of a medium size skillet with oil. Bring to medium high heat. Add rice and coat with oil, stirring occasionally until rice is a little whiter (about 5 minutes). Combine all other ingredients in a bowl and mix together then add mixture to rice. Reduce heat to low, cover, and let simmer for 15-20 minutes.
