I love theKellogs fibre plus bars. I think they are better than the hi fi's. They were on offer recently at tesco for 99p a box. They do a dark choc and almond and that is really lovely.
Aldi Benefit less than 70 calorie bar - are the same as hi-fi lights so you can have 2 per day of any flavour as a HEB or 1 = 3 syns (chocolate and orange is my fav!) x
