The apple pie flavour was my favourite out of the ones I've tried.
Quest bars are one of the best options when it comes to protein bars - but any protein bar is not a good option. Whole food is always superior. Protein bars should only be used once in a while as a treat or in an emergency because you can't get a meal in.
If you are looking for a meal replacement, a high quality whey isolate shake with rice cakes, a greens powder and almonds is a much better option.
