For each croque:
1 Take 3 pieces of toast bread.
2 Butter or spread with mayo.
3 Spread each slice with some grain mustard.
4 Generously layer sliced ham and tasty cheese on to
2 slices and stack up to make a 3 tier sandwich.
5 Make a mix of eggs and milk (as you would for French toast) and dip the triple deckers into this, allowing the bread to soak up the mix.
6 Seal each sandwich in a pan with a little oil and then place on an oven tray.
7 Bake the croques in a medium oven until the cheese is melted.
Serve with lots of paper napkins.
