Whisk very frequently until it reaches a boil, and then reduce heat to very low, continuing to whisk for a bit. Any combination is tasty. After the rice has cooked about 10 minutes, I quickly add diced onions, carrots, and red bell peppers. Ten minutes later, I add broccoli and dried herbs. Of course, the vegetables and the herbs can be varied.
Experimentation is fun.
I don't have any recipes for a low cost alternative. Let me share what I do. I go to my favorite supermarket that doubles coupons up to a dollar. When they run these items on sale, I stock up. It is worth using these coupons.
