Soak paneer in hot water for 20 minutes. I love Haldiram's brand.
Chop the ginger and garlic.
Prepare the marinade with yogurt, salt, turmeric powder, Kashmiri red chili powder, ginger, garlic, and lemon juice.
Slice the paneer into half-inch slices, you can make them a little thicker if you prefer.
Chop the onion into half-inch cubes.
Chop the red and green bell peppers into half-inch cubes as well.
Add the paneer along with the onion, red and green bell pepper to the marinade. Refrigerate for 20-30 minutes.
In the meantime, ground the whole spices in a coffee grinder.
Pulse until pulverized. Set aside.
