I think gammon joints are pretty reasonable myself. So boil it or roast it on the Sunday, and serve with mashed potatoes and veg. Do a mustard and chive sauce as well. And make double the amount.
On the monday or later in the week, chop up the rest of the gammon, and cook some pasta. Then in a nice shallow oven dish mix cooked drained pasta with gammon and some grated cheese. I like Gruyere, but cheddar would be fine. I also mixed a little bit of creme freiche with dijon mustard in to the pasta. Then pour left over mustard and chive sauce on top. Bit of grated cheese (parmesan, or cheddar) on top if you are feeling esp indulgent and put it in a medium oven for 20 -25 minutes to brown on top.
How to make mustard and chive sauce a la Overrun.
Roux sauce, so big knob of butter melted in a sauce pan and add a generous amount of dijon mustard. Then add a tbs of plain flour take off heat and stir in, keep adding flour until you get a thick sticky paste. Back on the heat. Then add your milk little by little stirring all the time, prob about a pint in all. This will thicken, then add lots of finely chopped chives at the end.
