For the best texture, use just-ripe avocados that yield slightly to gentle pressure without feeling mushy. You can prepare the chicken salad up to two days in advance and store it covered in the refrigerator, then fill the avocados just before serving to minimize browning. For extra flavor variations, try adding a pinch of smoked paprika, a splash of hot sauce, or a tablespoon of chopped sugar-free pickles to the chicken salad. This recipe is very macro-friendly for keto and can be paired with a simple green salad or sliced cucumbers for added crunch without adding many carbs.
