I bought these primarily as non-perishable back up food. At 220 calories for the tuna salad and 80 calories for the crackers, it is a snack or small meal that might satisfy your hunger for a while. The 170 fat calories will slow your digestive system as though you had eaten a larger meal. I would like more tuna and less mayonnaise. A higher percentage of carrots and celery would help. It isn't perfect but I like it and will buy more.
