2 slices of toastbread

1 slice of ham

2-3 slices of Gruyére

1 tbs. mustard 

butter

I watched Rachel Allen on BBC and I took the fancy of this sandwich of hers. Butter one of the toastbreads, put the ham and the cheese on it. Spread the other toastbread with mustard and cover the other with this. Butter one side of the sandwich and toast it to golden brown in a non stick frying pan. Meanwhile it's frying in the pan, butter the other half as well and when the first side is ready, turn and toast the other side to golden brown as well. Serves one.
