Pair the 4 slices of bread into two sandwich sets. Divide the mango chutney (2–4 tablespoons total) so each sandwich gets about 1–2 tablespoons.

Spread the allotted chutney on one slice from each pair, then place the remaining slice on top so the chutney is inside the sandwich. Press gently to seal.

Heat a clean, dry skillet or frying pan over medium heat until hot (about 2 minutes).

Place one or both sandwiches in the pan (cook both at once only if they fit without overlapping). Cook until the bottom is golden brown, about 2–4 minutes.

Flip each sandwich and cook the other side until golden brown and the sandwich is heated through, another 2–4 minutes.

Remove sandwiches from the pan, let rest for about 1 minute, then cut and serve.
