Add the rice and gently stir for about 8-10 minutes until the rice starts to brown and looks golden in color.
Add the tomato sauce, vegetable stock, garlic, cumin, salt and pepper to the skillet. Give the mixture a stir.
Cover and bring to a simmer for 15-25 minutes or until the rice is cooked and the liquid is absorbed.
Different types of rice will need slightly different amounts of liquid to cook. Some require 2 cups of liquid for 1 cup of rice and some require 1.5 cups of liquid for 1 cup of rice. If your bag of rice calls for 2 cups of water for 1 cup of rice, then add 4 cups of vegetable stock instead of 3 cups.
