I was given this recipe a long time ago. I wonder why the sauce is not made with regular flour like a regular béchamel..But I guess both can work. This can be a side dish or a main…

The haricot bean, navy bean, pearl bean, Boston bean, white pea bean, or pea bean is a variety of the common bean. It is a dry white bean that is smaller than many other types of white beans, and has an oval, slightly flattened shape. This recipe comes from a good friend in Wales it is a wartime recipe which has been adapted slightly. It is very thrifty but surprisingly good to eat.
