After reading the ingredients on the back of refried beans, I decided to lighten it up!
In a sauce pan, combine:
1 can of beans, drained and rinsed (we usually use pinto beans but I've also done white kidney beans)
Enough water or broth to cover the beans
Bring to a boil, reduce heat and let simmer for 10 minutes or so: just enough time for the beans to soften up.
Then mash them!
