Different greens, i.e. lettuce, romaine, green peppers, tomatoes, a type of bean, i.e. garbanzo, kidney (or a three bean type mix), red onions, cucumbers, crotons, mushrooms, broccoli, cauliflower, shredded carrots, shredded cheese, and a selection of dressings. Cottage cheese is not a bad choice.
Daily I make a salad my lunch. I'll add chopped chicken and black olives to the mix too.
