What are "B/E-inch slices"?
It seems that B/E is a corruption of ¼ (as MaxW has suggested in a comment).

A Google search for "B/E- inch slices" finds https://www.drperlmutter.com/recipe/zucchini-yogurt-gazpacho-saffron-marinated-chicken-breast/ (which I guess is what you are trying to follow), but it also finds the PDF file http://www.fasttracktohealth.net/members-only/grainfreerecipes.pdf (which contains exactly the same recipe). If you download that PDF file, you’ll find that the text actually says "¼-inch slices" - but copying and pasting that piece of text gives "B/ E" instead of "¼" (due to some peculiarity of the font encoding).
