"I found all the ingredients at my local megamart except for the silken tofu. I substituted low fat yogurt for the tofu and the bars came out great. I didn't recalculate the nutritionals on them (and I'm sure I pushed up the cholesterol a little), but I shouldn't be too far out of the healthy-within-reasonable range. I'm not a big fan of dried blueberries, so I might double up on the dried cranberries next time. Great concept and obviously the recipe is moderately flexible to substitutions.
