Joanna,
Maybe you could use the lettuce as a wrap of some sort for a sandwich, or add bean sprouts to a salad for lunch. There are many different dressing options for salads such as oil and vinegar, hummus with a little water for a salad friendly consistency.
Salad Dressings:
1 cup 2 percent cottage cheese plus 1/2 cup unsweetened almond milk you get a base from which you can build a creamy dressing
Another is: olive oil, balsamic vinegar, garlic, and Dijon mustard.
2 tablespoons greek yogurt, splash of Stevia, and 1-2 tablespoons balsamic vinegar
Hummus and add water until its dressing consistency
