Here is a something we have done to make rapid refritos.
Take diced onions and saute for a minute or so in a frying pan in oil, butter, Crisco, lard or bacon fat (I prefer the bacon fat but anything works).
Then add a can or two of pinto or kidney beans, I would reserve some of the liquid.
As they warm, mash with a potato masher, adding additional liquid from the can as needed.
When the mixture comes to the right consistency, it is done.Toss in cumin, chili powder, hot sauce ad libitum.
At the end toss in some uncooked finely diced raw onions.
Put on a tortilla, top with some salsa, roll up and enjoy the burrito.
Or just use any way you wish.
Can do this in less than ten minutes and it is tasty.
Edited for spelling, I hate when I have to do that.
