Potaje is cuban poor folk food..you use beans ..( whatever kind..I use red beans )
Cook the beans until just tender ,
then saute onions peppers and garlic ..this is called a sofrito ( add whatever spices you like ..i use marjoram , cumin and oregano)..
Add all that in the beans throw in some bouillon cubes ,
or just use salt and water..whatever.
Then start cleaning out your fridge..
throw in whatever veg you have in there..
This is basically a bean stew. and it's addictive and good,
if you happen to have meat..throw it in the sofrito and saute it in there too .
Cook it until the flavors meld there's no right or wrong way..
