Use some of the left overs to make a ham puff pastry slice:
Ready rolled puff pasty, spread with caramelised onion chutney, scatter over the small pieces of ham, then any herbs (thyme / sage / parsley etc) and lay slices of cheese on top - we like brie or camembert but you can use whatever you like.
Bake in a hot oven till golden and crisp and the cheese is bubbling. Serve with salad - delicious! I always make this at Christmas!
