In a large pot, add boneless beef cubes, soaked chana dal, add whole spices-coriander seeds, cumin seeds and cinnamon sticks (In a cotton cloth like a potli), ginger garlic paste, turmeric powder, maggie chicken cube, roughly chopped onion, whole red chili peppers, and 1 litr water to cover everything. Cook covered on medium heat for 1 hour or until the meat is tender and the water dries up. During the last 15-20 minutes, stir frequently to completely evaporate any moisture.Remove the whole spice potli and let the mixture cool down. In a food processor, add the cooled beef and lentil mixture in batches, along with bread slices and process this mixture until smooth. And set aside in a large bowl.
Now add onion, green chilies, coriander leaves, mint leaves, small ginger chunk and oil in the food processor and grind them for a few seconds until they look thinly diced ( not like Paste). Now mix it in the beef mixture bowl.
Now sprinkle roasted and ground cumin and coriander seeds, garam masala powder, and 1 egg to the beef mix bowl, knead with your hands.
Lightly oil your hands and form the mixture into small, flat round patties, similar to hamburger patties. You will have around 30+ patties.
In a non-stick pan, add a little oil and cook the kababs on medium heat for 4-5 minutes or until they are golden brown on both sides and cooked through.
Serve hot with your favorite chutneys or dips.
