Brown rice and chick peas. Plenty of fiber, healthy, doesn't cost anything, and tastes great.
Make the brown rice per box directions.
For the chick peas, if you open the can, just dump it into a saucepan with maybe a tablespoon of garlic powder and almost a 1/4 teaspoon of red chili pepper flakes (check out penzeys.com, they are the best

If you have some frozen salmon burgers and toss them (once cooked) onto some nice whole wheat bread or a roll with a little BBQ sauce, you're full and happy. The rice can take 45 min to cook, but you can get everything else ready while it is simmering, and then it can all be hot and ready together. Or if you toaster oven cook the salmon burgers, they might be ready first.
Guy cooking at its best, but the family likes it.
