Notes
For the best texture, choose avocados that yield slightly to gentle pressure without feeling mushy. If preparing ahead, mix the tuna, mayonnaise, lime juice, salt, and pepper up to 2 days in advance and store covered in the refrigerator, then cut and fill the avocados just before serving to avoid browning. For a different flavor profile, you can substitute lemon juice for lime juice using the same amount, keeping the recipe keto-friendly and bright.
