I would never have something as big and full of carbs as a jacket potato as a snack! A snack to me is something like a biscuit, fruit or yoghurt . . . .
I think it depends what you have with it,and what your diet preference is.I know I was brought on spuds(however they where cooked) as a thing that when with your meat and veg as a meal,but jacket spuds with say chilli or bolognaise poured over it can be very filling.
Each to their own.....but I am hungry now
Thing is then the lovely crunchy skin on the jacket spud(which I think is the best part)gets soggy cos I never get the plates dry properly.
Disaster zone ;( that's me!
We always had/have warmed up plates when at Mum's but she goes spare if I don't heat them when she visits, so I don't heat them. Serves her right for all the burnt fingers when I was a kid! Have had a plate crack in the oven so I don't bother. Dad and other half eat so quick food doesn't have time to get cold anyway. In my house, if you don't eat it when you get it, you don't get it!
