My favorite way to make pinto beans...with a little spice!
Sort and rinse the beans to remove any debris
Place the rinsed beans in a large bowl
Cover the beans with 6 - 8 cups of cold water
Add garlic and bay leaf and allow to soak overnight
Drain and rinse the soaked beans
Heat the olive oil over medium heat, in large pot
Add the onions and saute until soft
Stir in the garlic, oregano, cumin, jalapeno peppers and saute for about a minute
Add the beans, chicken stock and water
Bring to a simmer, cover and allow to cook for an hour
Remove the jalapeno peppers
Stir in the brown sugar, salt and vinegar
Simmer, uncovered, for another 45 minutes or until the beans are nice and tender and the liquid has thickened
Add salt and pepper to taste
