Maybe, but not for emergency food
To be fair, I got this product because I thought I could use it in emergency food supplies.  Bread products with long storage life are hard to find.  For its intended special uses it may do very well.  For my purposes, I found baking bread and Mountain House Pilot Bread to be better solutions.  I gave it three stars because it did perform as described but I did not care for the flavor or lack of firmness.  Some more experimenting might have led to improvements in flavor and how well it worked for sandwiches.
Rating: 3 stars
