Grilling and barbecuing don't have to be all about burgers, steaks, and hot dogs; vegetarian burgers are easy to make and easily customizable. Vegetarian burgers can be made using virtually any mix of beans and vegetables; whatever you have on hand will work. This recipe uses chickpeas, onions, and cumin; after the patties are grilled they're super smoky and flavorful.
Combine all the ingredients in a large bowl. Use your hands to mix, mashing some of the beans as you go. Form the mixture into 4 patties.
Grill the patties until they are cooked through, about 3—4 minutes per side.
In a medium bowl, combine the yogurt, lime juice, and cilantro. Season with salt, to taste.
Top the grilled burgers with the yogurt sauce and red onion slices. Serve on miniature whole-wheat pita.
