In a pan, dry roast the green chilies, garlic, peanuts, and cumin seeds, for 2 – 3 minutes or until they are fragrant. Let the mixture cool slightly.
In a mortar and pestle (or a grinder), combine the roasted ingredients with fresh coriander and salt. Pound or pulse until you have a coarse, rustic paste. Add a squeeze of lime juice, gram flour, and sesame oil. Mix well.
Cut block of paneer into square pieces with half inch of thickness. Take a tablespoon of thecha and gently press it around the paneer, nsuring each cube is evenly coated.
Heat a grill pan over medium-high heat. Brush or spray the pan with oil. Place the marinated paneer cubes on the grill pan or grates.
Grill for 2-3 minutes on each side, or until you see beautiful grill marks and the paneer is slightly golden and cooked through. Be gentle when flipping the paneer to keep the pieces intact.
Once the paneer is grilled to perfection, transfer it to a serving plate. Serve warm with dip of your choice.
