Another find on my last trip to Cost Plus World Market was single serving size shelf stable sausages by Smoky Valley. Cost Plus has a couple flavors but you can also find them easily through one of our favorite online retailers, Minimus (Let us not forget that $20 gets ya free shipping through them!).
The sausages are easily opened (pull and tear style) and weigh in at 1 3/4 ounces each. The perfect amount with a piece of string cheese or similar and some crackers for a quick lunch on the trail.
