Four words… 205 calories per ounce.

Do we have your attention now?? If you’re a keto backpacker, this tuna salad is not your average keto backpacking meal.

Sorry to nerd out there . . .

We know not everyone gets as excited about ultralight meals as we do. But this one has a lot going for it. Not only is it ULTRA ultralight, but it’s very low volume (great bear can stuffer) and an excellent source of protein with 19 grams per serving.

Did you know that tuna packets, on average, provide only 27 calories per ounce? That’s because of the significant amount of water in the packets. By dehydrating canned tuna or tuna packets, the caloric density of the tuna is increased to 125 calories per ounce!

    INGREDIENTS
     

    OPTIONAL

    INSTRUCTIONS (per serving)

    HOME

    • Put the dry ingredients in a bag or container to be used in the backcountry. See meal prep tips below.
    • Pair with 1 packet (14 g) of mayonnaise to be added when the meal is rehydrated.

    FIELD

    • Add enough water to cover the tuna mixture and stir to mix well.
    • If using cold water, let the meal stand for 30-60 minutes, allowing the meal to rehydrate fully. If using hot water, let the meal stand for 10-15 minutes. Rehydration times will be much shorter if freeze-dried tuna is used.
    • Once the meal is rehydrated, properly drain any excess water following the Leave No Trace (LNT) principles.
    • Add 1 packet (14 g) of mayonnaise and stir to mix well.
    • Pair with your favorite crackers, wrap, or pita bread and enjoy!

    NOTES

    MEAL PREP TIPS

    • If preparing the meal for long-term storage, we recommend packing the parmesan cheese in a separate container just before leaving for the trip. This will greatly lengthen the shelf-life of the meal. Single-serving packets, such as those used by pizza restaurants work well.
    • This is a low-volume meal. Consider making two batches for a hungry hiker.

     

    INSTRUCTIONS FOR DEHYDRATING TUNA

    • Here’s a detailed how-to guide on dehydrating tuna for backpacking meals.
    • Drain the juice from the can or pouch.
    • Transfer immediately to dehydrator trays.
    • Dehydrate at 145-155℉ (62-68℃) until completely dry.
    • Allow the dried tuna to cool for 30-60 minutes.
    • Package in an airtight container.
    • Dehydrated tuna is shelf-stable at room temperature for 1-2 months, 6 months in the refrigerator, or up to one year in the freezer. Freeze-dried tuna stored in an airtight container is shelf-stable for 10-15 years.
