Gail's Seven Layer Salad is a classic American dish that is perfect for potlucks and gatherings. It features layers of crisp lettuce, juicy tomatoes, crunchy bacon, hard-boiled eggs, sharp cheddar cheese, and a creamy mayonnaise-based dressing. The layers are visually appealing and the combination of flavors and textures is delightful. This salad can be made ahead of time and stored in the refrigerator until ready to serve.
