In a blender, add 200 grams of fresh coriander leaves, 100 grams of mint leaves, 2-3 green chilies, 1 tablespoon ginger-garlic paste, 1 tablespoon lemon juice, 1 teaspoon chaat masala, salt to taste, and 2 tablespoons of water. Blend until smooth to make a green marinade.
In a mixing bowl, add 500 grams of cubed paneer, 1 chopped capsicum, 1 chopped onion, and the green marinade. Mix well, ensuring that the paneer and vegetables are well coated. Cover and refrigerate for at least 30 minutes.
Preheat the oven to 200°C. Skewer the marinated paneer and vegetables onto wooden or metal skewers, alternating between paneer, capsicum, and onion.
Place the skewers on a baking tray lined with aluminum foil. Brush the paneer and vegetables with 2 tablespoons of oil.
Bake the skewers in the preheated oven for 15-20 minutes, turning them halfway through, until the paneer is golden and the vegetables are cooked.
Remove from the oven and serve hot with mint chutney or yogurt dip.
