Pulse the chickpeas with scallion and salt until a chunky mixture forms. If you are using rolled oats, then add them along with the chickpeas here.
In a mixing bowl, combine the chickpea mixture along with basmati rice, grated carrot, dried breadcrumbs, cilantro and 2tbsp yogurt sauce.
Mix well and divide the mixture into 4 equal parts and form into patties.
Heat 2tbsp olive oil in a nonstick skillet and gently place the burger. Cook the burger on medium flame, without disturbing, for 3~4 minutes until it is golden and firm. Flip and cook on the other side for another 3~4 minutes until golden. Top with yogurt sauce and a serve with a simple salad.
