Low-carb and keto-friendly, this Avocado Tuna Salad is a bright and refreshing meal option, perfect for lettuce wraps! Plus, it’s super portable and convenient for any picnic, BBQ, or potluck party.
I am such a simp for tuna salad.
My version is usually super simple (think tuna + mayo + celery), but after combining it with avocado, dill pickles, lime juice, I can honestly say I’ll never go back to my old ways.
Every few years, when I have a freakout over 30-something weight gain, I try to cut some carbs out of my life. I thought to try this on lettuce “wraps” (which honestly ate more like tacos but whatever) and OH MY. The crispy lettuce was so refreshing and was a perfect vessel for this delish tuna salad.
Perfect picnic food, my friends. Just think – no soggy tuna bread!

See? Tuna tacos, and I don’t mean the kind that Kay’s Cooking makes on YouTube.
