Cooked a gammon ham today knew it would make a few meals so dinner tonight and used the stock to make soup too.(Thats another post : )
The onion sauce is really tasty makes a change from parsley sauce with ham.
Onion sauce
1 pint 1% milk
1tbsp corn flour
1/2 tsp salt
1/2 tsp pepper
2 large onions (finely chopped )
1 bay leaf

Place milk and onions and bay leaf in a large saucepan bring to the boil and then leave to cool.
When ready to serve add corn flour and seasoning and whisk to combine. Keep whisking over a medium heat until thick and simmer for a few minutes taste to check for seasoning.(remove bay leaf)

I served this with dinner tonight thick slices of the home cooked ham with new potatoes (the last from the garden alas) baby peas, carrots and broccoli .

The dinner is syn free but the sauce (to serve 4) works out at 4 syns per portion.
