Heat oil in a 3-quart saute pan over medium heat. Stir to combine and ensure all grains are coated.
Add the long-grain white rice and stir frequently for about 3-5 minutes until the rice begins to turn a golden color.
Add chili powder, Caldo de Tomate, and minced garlic. Stir well to combine all ingredients.
Pour in water and canned tomato sauce while stirring gently.
Bring the mixture to a boil, then reduce heat to low and cover. Allow it to simmer for about 20 minutes until all water has been absorbed.
Turn off the heat but let the rice rest covered for another 5-10 minutes.
Fluff the rice gently with a fork before serving.
