For food safety, use pasteurized egg yolks in the dressing if you are concerned about raw eggs, or substitute egg yolks with about 1/3 cup of high-quality mayonnaise and reduce the olive oil slightly as needed for a thick, creamy consistency. To keep the salad crisp for meal prep, store the romaine, bacon, avocado, and dressing separately and combine them just before serving, adding the avocado at the last minute to prevent browning. If you want to turn this salad into an even more substantial main course, top each serving with grilled chicken, shrimp, or sliced steak, making sure any marinades or seasonings do not contain added sugar. Leftover dressing will keep in an airtight container in the refrigerator for up to 3 days, and it may thicken as it chills, so whisk in a small splash of water or lemon juice to loosen it just before using.
