Heat oil in saucepan over medium heat. Add vegetables and garlic; stir, cover and cook 6 minutes.
Add drained beans and mix. Incorporate remaining ingredients. Gradually pour in enough cold water to cover beans by 254 in (6.5 cm). Season generously with salt and pepper.
Cook, partly covered, 2 1/2 hours over medium heat. Stir several times, adding more water as needed.
