You can cook the kidney beans alone - then use the cooked kidney beans in the recipes that specify cooked beans.
The reason I say that is because it's difficult to cook the dry beans, even after soaking, in anything but very long cooking stews. The other ingredients have to cook along with the beans and that is usually a long time. It depends on how many beans you are using, but kidney beans take a while! On the other hand, cooking them, and using x amount of cooked beans, is easy - especially if you have them cooked and refrigerated, waiting to be used.
Kidney beans are high in protein but they also have a good amount of calories. You can make a salad with other fresh veggies and mix with a little oil and vinegar. I like them with walnuts but walnuts are pretty caloric, too. So, the 400 calorie limit means smaller portions.
