3cups cooked pinto, red, or black beans, drained but still moist
Salt and pepper
1/4 teaspoon cayenne, plus more if desired
Instructions
Put the oil in a large skillet over medium heat. When it’s hot, add the onion and cook, stirring, until golden brown, 10 to 12 minutes.
Add the cumin and cook, stirring, for 1 minute more. Add the beans and mash with a large fork or potato masher. Continue to cook, mashing and stirring, until the beans are more or less broken up (some remaining chunks are fine).
Sprinkle with salt and pepper and add the cayenne and more cumin if you like. Taste, adjust the seasoning, and serve.
