VERY tasty and indulgent almost. Best protein bars I've tasted to date

It is so great to find a protein bar which is vegetarian, but also delivers high protein and tastes great. So many protein bars are a bit claggy and heavy, but this is lovely and the crispiness helps lighten the texture. This is my go-to when I want to add extra protein to my day.
