Brush one side of the bread slices with mayonnaise and the other sides with the chutney. Melt the butter in a non-stick frying pan over a low heat and lay two of the bread slices in the pan, mayonnaise-side down (or do this in batches, if your pan is not big enough to hold both sandwiches at once).

Mix all of your cheese selection together, then sprinkle half over the chutney. Sandwich with the remaining bread slices, chutney-side down. Weigh down with something heavy (a second smaller pan works well). Cook for 5-6 mins on each side until the bread is deeply golden and the cheese is melted and gooey. Leave to cool slightly, then slice in half and serve.
