A lightly grilled naan, topped with a juicy burger and cool, tangy cucumber raita, brings together the best things about a burger and the bold flavors of India in only 20 minutes.
In a medium bowl, stir together the Cucumber Raita ingredients: yogurt, cucumber, cilantro, green onion, salt, pepper, and garlic powder. Set aside.
Preheat oven to broiler setting.
In a medium bowl, combine the ground venison with garam masala, salt, onion powder, garlic powder, cumin, black pepper, coriander, and 2 tablespoons melted butter. Divide the meat mixture into four equal portions, then flatten each into a patty about 4 inches wide and ½ inch thick.
Add the oil to a 12-inch skillet and heat over medium until hot and shimmering but not smoking. Working in batches if needed, add 4 patties to the pan and cook until the underside is browned with a slight char, 3 minutes. Flip the burgers and cook until done to your liking, about 2 minutes more. I like my venison burgers cooked to 130 degrees F using an instant-read meat thermometer if they contain 100% ground venison, not pork. Transfer burgers to a large plate and let rest for 3 minutes while you toast the naan.
Brush the top of each piece of naan using the remaining melted butter and place on the middle rack of the oven under the broiler setting and toast for 2 minutes.
Season each slice of tomato with a pinch of salt and black pepper.
Top each piece of naan with ¼ cup shredded lettuce, a slice of tomato, 2 tablespoons of crumbled feta cheese, a few pieces of sliced red onion, a cooked burger patty, and 2 Tablespoons of cucumber raita. Top with another piece of naan and serve.
