Step 1: Dry Roast Spices

Dry roast 3 tsp cumin seeds, 1 tsp fennel seeds, 5-6 cloves, 1 tsp peppercorns, and 2 thin strips of cinnamon in a pan for about 2-3 minutes until aromatic. Turn off the stove and allow the ingredients to cool completely.

Step 2: Grind Masala Powder

Transfer the cooled spices to a mixer grinder. Add 1 tsp amchur powder and 1/2 tsp black salt. Grind everything together to a fine powder. Remove the masala powder from the mixer jar and keep it aside.

Step 3: Prepare Mint Coriander Chutney

In a mixer grinder, add a handful of mint leaves, 1/2 bunch of coriander leaves, 3 green chillies, 1 inch chopped ginger, juice of 1/2 lemon, and 1/2 tsp black salt. Grind everything together. Add 1 tsp of water and grind again to a smooth paste. Remove the chutney from the mixer jar and keep it aside.

Step 4: Assemble First Layer

Take three slices of white sandwich bread. Spread a generous amount of unsalted butter evenly on one side of two bread slices. On the buttered side of the first bread slice, spread a generous amount of mint coriander chutney. Place sliced boiled potato on top of the chutney and sprinkle some of the prepared masala powder over the potato slices. Place sliced fresh onion on top of the potato and sprinkle more masala powder over the onion slices.

Step 5: Assemble Second Layer

Place the second buttered and chutnied bread slice on top of the onion layer, with the chutney side facing down. Spread more butter on the top side of this second bread slice. Spread another layer of mint coriander chutney on the buttered side. Place sliced fresh tomato on top of the chutney and sprinkle masala powder over the tomato slices. Place sliced fresh cucumber on top of the tomato and sprinkle more masala powder over the cucumber slices.

Step 6: Add Cheese and Close Sandwich

Finish by adding a generous amount of grated mozzarella cheese on top of the cucumber layer. Take the third bread slice, spread butter and mint coriander chutney on one side. Close the sandwich with this final bread slice, chutney side facing down, pressing gently.

Step 7: Grill the Sandwich

Heat a grill pan and spread a generous amount of unsalted butter. Place the assembled sandwich onto the grill pan. Brush some butter on all sides of the sandwich. Grill for a few minutes until one side turns to a nice golden brown color with grill marks. Gently flip the sandwich to the other side. Brush some more butter onto the pan and the sides of the bread. Continue grilling until the other side is also golden brown and the cheese is melted.

Step 8: Serve Hot

Remove the grilled sandwich from the pan. Cut it into half diagonally and serve hot.

• Make sure you have all your elements ready before you assemble the sandwich.
