Slow Cooker White Beans with Smoked Ham Hocks

Cut the onion into medium (1/2-inch) dice. Peel the carrots and cut them and the celery into approximately 1/2-inch pieces. Coarsely chop the garlic.
2 medium onions, 2 large carrots, 4 ribs celery, 6 garlic cloves
Place a skillet over medium high heat. Add the olive oil, swirling it to coat the pan. Add the onions, carrots, celery, garlic, and thyme.
2 tablespoons olive oil, 1 teaspoon dried thyme leaves
Cook, stirring frequently, for about 10 minutes or until the onions begin to appear translucent.
Place the vegetables along with the ham hocks, beans, and chicken stock in a large (6-quart or larger) slow cooker.
3 large meaty smoked ham hocks, 1 pound dried Great Northern beans, 6 ½ cups chicken stock
Cook on low for 8 hours.
About 1 hour before the cooking time is complete, remove the ham hocks from the slow cooker and let them cool until they can be handled. Remove and discard the bones, fat, and skin from the ham hocks. Chop or shred the meat and return it to the slow cooker with the beans.
Add the salt and continue cooking until the beans are completely tender.
2 teaspoons salt
Garnish individual servings with diced fresh tomato, diced red onion, and/or snipped chives.
