Ex Input:
Of the few Hot Cocoa flavors we've tried, this is the best so far.  It has the richest flavor and I dont notice the artificial taste that others have commented on.  Its also very affordable compared to other k-cups right now.  I thought that the k-cup making process must have gotten more expensive over the last year, but now I know they are truely sticking it to us since these are still reasonable priced.

This mix makes GREAT belgian waffles.  We tried biscuits and pancakes and we do far better form scratch with a standard GF flour.  It does make seriously great waffles though, and we go GF/DF on these.  The waffles freeze extremely well and reheat in the toaster quite nicely.

I expected from the extremely positive reviews on the site for full flavor healty chips. In reality I get an OKAY taste with a strange aftertaste on basically all of the flavors. Chedder and Salt&Pepper honestly being some of the worst tasting chips I've ever had. If you're just looking for a great tasting brand of chips with health as a #2 on the list there are much much better brands out there. In the end I compare these chips to diet soda vs regular; Some won't tell the difference while some will immediately sense it and hate it.
