In a mixing bowl, mash the boiled rajma thoroughly.
Add mashed potatoes, chopped onions, green chilies, ginger garlic paste, besan, cilantro, garam masala, red chili powder, cumin powder, and salt to the mashed rajma. Mix well to form a smooth mixture.
Divide the mixture into small portions and shape them into round or oval kebabs.
Heat oil in a pan for shallow frying.
Place the kebabs in the hot pan and cook until they are golden brown on both sides.
Serve hot with mint chutney or yogurt sauce.
Notes
Don't over-mash the beans and potatoes. Leave some small chunks for a satisfying bite.
Drain canned beans well. Excess liquid can lead to mushy patties.
Chill the formed patties for 10-15 minutes. This helps them hold their shape during cooking.
Don't overcrowd the pan when frying. Also, flip gently using a spatula to avoid breaking the patties.
