Step 1: Prepare a mixture – Add boiled potato to a bowl. Now add chopped onion, boiled peas, salt, chaat masala, black pepper powder, garam masala and red chilli powder. Mix well to prepare a mixture.
Step 2: Make a sandwich – Now spread one tbsp ketchup on one slice and one tbsp mint chutney on another slice. Use half the mixture and spread on one slice. Top it off with another slice. Press it down a bit to prepare a sandwich. Make one more sandwich by repeating the step.
