For meal prep, store the chicken, bacon, almonds, dressing, and chopped romaine separately in airtight containers in the refrigerator for up to 3 days, and assemble just before serving so the lettuce and almonds stay crisp. To vary the flavor, you can substitute boneless skinless chicken thighs for the breasts, swap the almonds for pecans or walnuts, or replace Parmesan with Asiago or Pecorino Romano while keeping carbs low. If you prefer a thinner dressing, whisk in 1 to 2 tablespoons of water or additional lemon juice until it reaches your desired consistency without adding carbs. Always check labels on mayonnaise, mustard, and Parmesan to ensure there is no added sugar so the salad remains strictly keto friendly.
