  3. COMBINE INGREDIENTS: Add the drained tuna, mashed avocado, chopped veggies & remaining avocado, Dijon, fresh lemon, salt and black pepper to a large bowl and use a fork or spoon to toss and combine.

  4. SEASON: Taste and adjust seasonings by adding more salt, pepper and Dijon mustard to taste.

  5. ENJOY RIGHT AWAY: You can eat it straight out of the bowl or chill in the fridge for at least 1 hour.

  6. TO CHILL IN THE FRIDGE: Cover with plastic wrap or store in an airtight container with a lid and refrigerate for 1 hour or up to 3 days.

  7. SERVE: Serve over a salad, in lettuce wraps or stuffed in avocados for a Whole30, Paleo or Low Carb version.

    FOR THOSE THAT DO NOT HAVE DIETARY CONCERNS: You can also make tuna salad sandwiches or tuna melts that you can make using your favorite keto bread.
