To keep this salad crisp for meal prep, store the grilled chicken, chopped vegetables, and dressing in separate containers and combine them just before eating. Use chicken thighs for maximum juiciness and flavor, and do not be afraid to develop deep char marks on the grill for that signature smoky, fire-roasted character. If you prefer to lower the carbs even further, reduce the cherry tomatoes and bell pepper slightly and increase the cucumber and romaine to maintain volume and crunch. This salad keeps well in the refrigerator for up to 3 days when stored in airtight containers, though avocado is best added right before serving to prevent browning.
