Step 1: Prepare the Marinade : In a bowl, combine yogurt, ginger-garlic paste, red chili powder, turmeric, garam masala, cumin powder, chat masala, lemon juice, oil, and salt. Whisk until smooth.
Step 2: Marinate Paneer and Vegetables : Add paneer cubes, bell peppers, and onion wedges to the marinade. Toss gently to coat evenly. Cover and refrigerate for at least 1 hour (up to 4 hours for best flavor).
Step 3: Assemble the Skewers : Preheat your grill, oven, or stovetop pan. Thread paneer, bell peppers, and onion alternately onto skewers. Brush lightly with oil.
Step 4: Cook the Skewers : Grill method: Grill skewers on medium heat for 10–12 minutes, turning occasionally until charred and cooked. Oven method: Preheat oven to 400°F (200°C). Place skewers on a baking sheet and bake for 15–20 minutes, turning halfway. Pan method: Cook on a non-stick pan with a little oil over medium heat, turning carefully until golden brown.
Step 5: Prepare Mint Chutney : In a blender, combine mint, cilantro, green chilies, ginger, lemon juice, sugar, salt, and water. Blend to a smooth consistency. Adjust seasoning.
