For food safety, you can use pasteurized egg yolks in the dressing or replace the yolks with 1/4 cup mayonnaise while slowly whisking in the olive oil for a similar creamy texture. Make sure the romaine is very dry before dressing to keep the salad crisp and avoid watering down the flavors. The grilled chicken and Caesar dressing can be meal-prepped up to 4 days in advance and stored separately in the refrigerator, then combined with freshly chopped romaine and crunchy toppings just before serving for best texture. To keep carbs low, avoid store-bought Parmesan blends with starch or fillers and choose plain, freshly grated Parmesan.
