If you make this, don't add the tomato sauce or canned tomatoes until the very end when the beans are completely cooked. I soaked my beans overnight, then put the ingredients in a crockpot. It's been cooking for 10 hours on high and the beans are hard as rocks. I googled dry bean tips and read that you should never put anything acidic (like tomatoes) with beans until the beans are almost completely cooked. The acid slows down the absorption of liquid. I'm going to leave the crockpot on for another few hours - I hate to lose the whole batch of ingredients. On the positive side, it smells great, if only the beans get done.
