If you think lamb’s too gamey, these retro-inspired zucchini boats will win you over. The addition of ground beef and creamy lentils combined with fragrant cinnamon and allspice make this taste exotic and comforting at the same time. If you’re still on the fence, ground sirloin is an equally tasty substitute. Though you might be tempted to drain the pan before stirring in the lentils, don’t—the juices add rich flavor to the finished dish. A drizzle of the yogurt sauce ties it all together; serve with whole wheat couscous for a little extra fiber.
