Saute onion in oil over medium heat. Cook until tender, about 5 minutes.Mix rice into skillet, stirring often. When rice begins to brown, stir in chicken broth, salsa, garlic salt and cumin.Reduce heat, cover and simmer 20 minutes, until liquid has been absorbed.I double this recipe to make a lot of rice. You do the work once and have enough to last my family 2-3 meals.I let rice cool and then freeze in freezer bags, that way I only have to mess up the kitchen once for a few extra meals.Now that you have it cooked and in freezer, you are ready to an easy night of cooking.Take rice from freezer baggy and place in microwavable dish. Add a small amount of water and cover.Cook for about 3-4 minutes until warm.
