Mash the Paneer and mix it with the potato. Heat oil and add jeera; once it crackles, add ginger and green chilli. Toss them for a few seconds, add the turmeric, and immediately add the Paneer-potato mixture.
Add salt to taste. Toss for 2-3 mins and take off the flame. Spread out on a tray and allow to cool completely. Add bread crumbs, chopped coriander, and almonds to the mix, and make round and flat patties. Roll the sides of the patty with some almonds and keep aside.
Heat the remaining oil in a pan and cook the patties on both sides till golden brown.
Pan-fry the marinated paneer slices on a grill pan or a non-stick pan till golden brown marks appear. Do not over cook and harden the paneer. Heat the sauce. Place most of the tomato sauce in an oven-proof flat dish or platter. Arrange steaks. Sprinkle the remaining sauce on the steaks. Sprinkle topping mixture.
Add the gattas, garam masala and mint and bring to a boil, cover and simmer for 10 minutes. Adjust the seasoning, garnish with grated paneer and coriander. Serve hot.
