Lentil Burgers with Tzatziki
In addition to providing protein and fiber, lentils are a significant source of folic acid. Even more folic acid comes from the wheat germ used to bind the burgers, and from the whole wheat buns. These burgers pack 143 micrograms of folic acid--more than one-quarter of a day's recommendation. Tzatziki, the garlicky Greek yogurt sauce, makes a healthful and tasty alternative to mayonnaise.
