Whole Wheat Pasta
An excellent staple for any pantry, whole-wheat (or multigrain) pasta has nearly three times the amount of fiber as regular pasta. Fiber lowers your risk for heart disease and diabetes and fills you up faster and for longer. This potentially means you'll eat less -- resulting in weight loss.
You'll get about seven servings from a typical box of pasta. At less than $2 per box, this translates to about 28 cents per serving. Not bad!
Grocery store marinara sauce tends to be inexpensive, too, so pair that with your pasta for a satisfying meal. Whole-wheat pasta also lends itself well to pasta salad. Dress it up with hard-boiled eggs, some tuna and a bit of oil and vinegar for an easy and healthy lunch.
