Pour dry pinto beans in crock pot. Cover with cold water about 2 inches over the beans. Cover and set sit overnight. BE SURE THE CROCK POT IS NOT ON!
In the morning, pour the beans into a large colander and rinse with cold water. Place back into crock pot and just cover the beans with water.
Turn on low and let cook until soft. Season beans with cooked bacon, cumin, onion, garlic, jalapeno, taco seasoning, salt or any combination thereof.
When they are soft, mash the beans with a potato masher and serve.
