Although you can use any frozen veggie burger you’d like, the flavors of Mediterranean chickpea burgers—made with spinach, tomatoes, and Greek spices—work particularly well here. We found that toasted or grilled English muffins make a great substitute for a hamburger bun; the craggy texture captures the tzatziki, a sauce made with yogurt, cucumber, and spices, perfectly without getting too soggy. It's pretty easy to find prepared tzatziki in markets, but you can make your own my mixing finely chopped or grated seeded and peeled cucumbers into plain yogurt and season with salt and pepper and a squeeze of lemon juice.
