Never underestimate the wide variety of food creations which can be made from raw vegetables. A head of lettuce is cheap and contributes to about three big salads and a few sandwiches. I usually avoid commercial salad dressing and use ketchup instead. Another way to spice up a salad is to add black pepper. Other spices, such as basil, parsley, and oregano, can enhance the flavor of salads or other raw vegetables.
Salsa is a nice addition to vegetables as well.
It tastes especially good on carrots and cucumbers. Sandwiches often provide quick meals and allow countless possibilities. Lettuce, cucumber, and tomato sandwiches go well with rye bread and a mustard spread. Tomato and grated carrot sandwiches make another nice combination. If I have some pizza sauce, I will add it to mushrooms and green peppers over wheat bread.
