To keep carbs strictly keto, measure tomatoes carefully and reduce the portion if you need even fewer net carbs per serving. For variety, swap the chicken for grilled salmon fillets or sautéed shrimp, keeping cooking times appropriate for each protein. If you prefer, serve the salad over extra chopped romaine and reduce tomatoes slightly to stretch the volume without adding many carbs. The dressing will keep in the refrigerator for up to one week; let it come to room temperature and shake well before using. For dairy-free or paleo variation, omit the feta and add diced avocado right before serving for creaminess and healthy fats.
