What’s in the Mix

Tricks for Tuna Salad Success
- Keto tuna salad tastes best when it’s made up to a day ahead and served extra cold. This allows the flavors to blend even more.
- Adjust the amounts of mayonnaise and mustard depending on how creamy you want the recipe to be.
Keeping It Fresh
Keep leftover keto tuna salad in a covered container in the refrigerator for up to 3 days. Stir in a dash of lemon juice to freshen the flavors before serving with cloud bread, on a bed of lettuce greens, or even spread into a stalk of celery for a quick and simple snack. Freezing tuna salad isn’t recommended since it will thaw out too watery.
