Rinse and sort your beans.
Do not worry about soaking your beans!! Pour them into the crockpot and cover with the water.
Cook on low all day.(or about 6 -8 hrs).
About 30 minutes before you are ready to start mashing them, you will add all the spices to give them time to give the beans a good flavor. (Don't put the spices in earlier, because you will wind up having to put more in later).
After 30 minutes turn off the crock pot and put in the sliced cheese.
Take a potato masher and mash the beans until there are almost no whole beans left.
