To keep this salad strictly keto, be sure to use a sugar-free balsamic glaze or make your own by gently simmering balsamic vinegar with a keto-friendly sweetener until reduced and slightly syrupy. If you prefer fewer carbs, reduce the amount of cherry tomatoes and increase the mixed greens and mozzarella. For easy meal prep, store the dressed salad base and sliced chicken separately from the basil and glaze, then combine just before serving for the best texture and freshness.
