Chilli cheese potato toastie

Put the potatoes in a large bowl and lightly crush with a potato masher (or roughly crumble using your fingers). Add the chaat masala and red onion; season and mix well. Set a large frying pan over a low-medium heat.

Put 4 slices of bread on a board and spread evenly with the green tikka masala. Divide the potato mixture on top, followed by the cheese. Press the remaining bread on top. Spread the tops of the bread with ½ of the mayonnaise, then, mayo-side down, put 2 sandwiches in the hot pan (you may need to do them one at a time).

Spread the tops of each toastie with 1 tbsp mayonnaise, cover each with a piece of baking parchment and put another clean frying pan on top with a couple of cans of beans or tomatoes in it to weigh it down. Cook for 2-3 minutes, then turn the sandwiches over, cover with the parchment and weigh down again, cooking for a further 2-3 minutes until golden and the cheese has melted. Repeat with the remaining sandwiches.
