Today salads are a course in a meal or they can be the main course. The wide variety of fresh vegetables, fruits, pastas, cheeses, fish, meats, eggs, and poultry allow countless choices. You will find a wide selection here. If you are serving a green salad do not settle for just iceberg lettuce with tomato slices.
Iceberg lettuce has a very mild bland flavor compared to other varieties.
So add some other salad greens. Those usually available include boston lettuce, Belgian endive, romaine, fresh spinach, watercress, and many others. You can also add slices of red onion, olives, sliced mushrooms, chunks of cheese, etc. There are many varieties of salad dressings available. Use a simple oil and vinegar, or experiment with any of the commercial varieties available.
