Dried beans are magical. What other protein and fiber source swells up to two or three times its original size when soaked in water. Think of what a hamburger would do if you soaked it overnight.
I did some pretty arcane calculations and found out that dried black beans and boneless skinless chicken breast each cost about 2 cents per gram of protein. Adults need about .8 grams of protein per every 1 kilogram of ideal body weight (1 kilogram equals 2.2 pounds). That’s about 55 grams of protein for a 150-pound person.
One 3.5 ounce chicken breast has about 45 grams of protein so if you eat that almost anything else is overkill. Not that chicken protein is a bad thing, but one cup of cooked beans gives you about 15 grams of protein and has the added benefit of providing about 15 grams of fiber.
Most people don’t get anywhere near the 20 to 25 grams of fiber needed per day and claim they would have to eat corrugated cardboard to reach the target. Not so. Soak some beans overnight, marvel at them in the morning, make this soup in the evening and get good low-fat protein and fiber.
This soup is very filling and makes a good main course to go with a salad.
