Saute onion, garlic. Add in spices, and shimeji mushrooms. Saute until mushrooms are cooked and add into the food processor.
Follow with chickpeas, cilantro, yogurt, salt and pepper. Mix on low until all combined and chickpeas are broken down into a smooth texture. Make sure not to pulse until it’s super smooth, it should look a little chunky. Take about 2 ½ tablespoons of chickpea mixture and roll into 4 balls. Flatten them slightly and set aside.
Marinade. In a medium bowl add all marinade ingredients and carrot. Marinate for 30 minutes or more if you have time.
Sauce. Mix all the ingredients and chill in the fridge until you fry the patties.
Meanwhile, in a nonstick pan, heat up cooking oil (about 2 inches of oil for more ‘’fried’’ effect) over medium heat and cook the patties for 5 minutes on each side or until crispy golden brown on top and bottom.
Assemble the burgers in buns with lettuce, sauce, and top with diced red onion and marinated carrot on top.
