In a large bowl, mix the ground beef with all the other ingredients except lemon juice, chaat masala, and oil.
Knead until the ground beef mixture is well blended. About 4-5 minutes.
Divide the ground beef mixture into golf-sized balls and form them into round burger-style patties. You should get about 8-10. I size them less than the regular burger size, but you can size them any way you want.
Set aside in the refrigerator for 15-20 minutes. You can also leave it overnight if you want to prep ahead.
Heat a heavy-bottomed skillet, griddle, or grill on medium heat. Grease with the oil using a paper towel or brush.
Place the tikkas on them and cook for approximately 8 mins, turning them halfway through until well browned and cooked. I like mine well done, so I tend to char them a bit!
Place on paper towels to soak up any excess oil or fat.
Move them to a serving dish and sprinkle them with a little lemon juice and chaat masala powder.
Garnish with chopped lemon and slices of red, white, or vinegared onions.
Serve with mint chutney, mint yogurt chutney, or a chili sauce, along with tandoori or naan bread, paratha, or roti. You can also use pita or any other flatbread.
