These nutrient-packed burgers are great for make-ahead meals.
To reheat them, put them in the oven at 350ºF until they're warmed through or heat them up in a skillet on the stovetop. (Your microwave will work too in a pinch, but they'll be a bit soft.) If you don't have buns, they're perfect on a bed of fresh greens or rolled up into a whole grain tortilla.
