No. I don't think I ever heard of eating beans on toast.
Generally, beans such as Great Northern (white) beans, are cooked slowly or pressure cooked and
ate with salt pepper in a bowl. Often to the side and/or in the bowl is onions. Cornbread is generally
a side with a bowl of beans. Many people that eat meat, place a slice or two of bacon or ham bones
to add a meaty flavor.
I like to eat Great Northern beans with onions and cornbread. I some times place worchestchire
sauce in mine. Worchestichire. WishTeaSheer
