Not much you can say about cold meat, curried eggs and potato salad, but:

Cold meat selection.

Ensure you have a selection. Ham rolled around asparagus is always popular. Just plain ham as well, for those who don't like asparagus.

Chicken loaf, medium cooked roast beef, and some mild salami makes a nice selection.

Curried (devilled) eggs are likewise popular and go well, in the end :)) with other's bum hummers.

Potato salad.

• Coliban or Desiree spuds are the best, I've found.
• Boil in their jackets, but don't overdo it.
• Peel when cold. Cut to size required.
• Make up a slurry of mayonnaise, sour cream, and stir together.
• Add some dry mustard, some white vinegar, some chopped chives, and a pinch of chicken salt.
• Stir all together and coat spuds with the mixture.
• Garnish with more chopped chives, although this is really a waste of time when the salad is rattling around in a fridge in the back of a Cruiser.
