A good cheese sauce can save any number of less-than-spectacular meals and snacks. If your chicken turns out dry and flavorless, or all you have is a bag of tortilla chips and some pickled jalapeños, a cheese sauce can swoop in to save the day. Roast beef sandwich? Put some cheese on it. Steamed broccoli? Cheese sauce. Plain old boiled noodles? Cheese sauce turns that into macaroni and cheese.
