¾cupOaxaca cheesefreshly shredded, may substitute with Mozzarella
Warm a small iron skillet over medium heat. Add the chorizo and cook until crumbly. About 8 to 10 minutes.
Once it's cooked through and crumbly, remove half of the chorizo and set aside.
Add the butter to the skillet with the remaining chorizo and allow it to melt. Then add the refried beans and mix them into the butter and chorizo. Periodically stir the beans allowing them to warm through. About 2 minutes.
Spread the shredded cheese over the top of the beans and sprinkle the chorizo you had set aside over the cheese. Reduce the heat to low and cook until the cheese melts completely. About 10 minutes.
