The Stable Chutney: Blend cilantro, chilies, garlic, masala, ice, and the bread slice into a thick paste. The bread ensures the chutney stays thick and doesn't make the sandwich soggy.
The "Dry" Veggie Mix: In a bowl, combine chopped onions, bell peppers, and corn. Add 2 tbsp of the green chutney, oregano, and chili flakes.
Note: Add salt and masala only when you are ready to assemble to prevent the veggies from releasing water.
Cheese Integration: Fold the grated processed cheese into the vegetable mixture until evenly distributed.
Triple-Layer Assembly: Butter three slices of bread. Spread the green chutney over the butter. On two slices, add a generous layer of the cheese-corn mixture.
The Protein Grate: Grate fresh paneer over the filling layers and sprinkle with a pinch of sandwich masala.
The Stack: Place one loaded slice on top of the other. Cap with the third slice (chutney side down) and press firmly.
The Weighted-Press Grill: Melt butter in a grill pan over medium-low heat. Place the sandwich in and top it with a flat plate and a heavy weight (like a heavy pan or stone).
The Golden Flip: Grill for 3 minutes until dark grill marks appear. Butter the top, flip carefully, and re-apply the weight for another 2–3 minutes.
Serve: Slice into triangles and serve with a side of extra green chutney and ketchup.
