We have often found mashed potatoes to be a bit of a mare to do in the van, (steam, cooking time etc.) so my thoughts turned to instant mash.
I used to use smash when tent camping, but it's not great, so I looked at other brands. The other day, Julie picked up a packet of this stuff;
Idahoan Classic Mash 180G - Tesco Groceries
Prepared in 1 minute, and it really is surprisingly good. It comes in various flavours, although we have only tried the original. I have to say, if I hadn't already been aware, I wouldn't have known it was instant.
It will be a great item to keep in the van. Anybody else tried it?
