When you think of vegetarian dinners, you probably don’t think of sloppy joes. But this recipe features a great stand-in for ground meat that packs plenty of protein: a mixture of savory California walnuts and chopped cauliflower. Simmered together in the signature thick, sweet sloppy joe sauce, it’s ready to be spooned into soft hamburger buns and topped with some pickle slices in just a few short minutes for lunch or dinner.
