Lentil crisps like Proper Chips, or Pop chips. I love their sour cream ones. They are below 90 cals.
Golden Wonder Ringo crisps. About 60 cals a bag. Get them in Home Bargains.
Rice stax sour cream. Home Bargains, about 90p a packet and get about 4 snacks from it. each little rice cake is only about 4cals or something like that. They are small but very tasty!
Milky Bar or Rolo mousse - think roughly around 70-85 cals, cant remember but very filling i find.
Cathedral City snack size cheese bags. Unreal and only 53 cals. Home Bargains, and only about 95p.
Slices of ham lol, no idea but it really fills me.
