#1. They are cheap.
#2. They are SO healthy.
I go as cheap as possible and buy them dry. I make massive amounts of beans and then freeze them so I always have them on hand. We generally only eat kidney and black beans. Maybe one day we will go out of the box and try some new ones.
Here is what I do.
#1 Get 2 lbs of beans.
#2 Soak them over night (follow directions on back of bag)
#3 Boil them for 1 hour and 40 minutes.
#4 Put them in 2 cup Ziploc freezer containers.
#5 Let them cool.
#6 Put them in the freezer for whenever you need them.
