I can tell you how to heat up a ham...

Just get some apricot jam or marmalade or even honey or maple syrup and mix some mixed spice in and slather it all over the ham. Make sure you cut the skin off not all the fat, so that you can score it and then slather it with the glaze. Don't cut the skin off at the bone (keep it on as a handle). Another glaze is maple syrup, brown sugar and a splash of orange juice. Heat up the glazes on in the saucepan and then paint them on the scored ham.

Time wise I'm not sure, you'll have to check that one out, I do know you can do it in a webber (not sure if you have one)

If you don't want the orange peel in the marmalade then heat it up in a pan and sieve it and it will remove the peel.

I do know stuff just not an exact recipe... KWIM...

We never stuff turkey rolls we get them pre stuffed.
