Congee is a rice soup or porridge. It has more the consistency of soup than porridge. I learned this recipe while living in Vietnam. Putting it in the slow cooker at night, I have a lovely breakfast in the morning, though it could be a wonderful, easy soup dinner with a salad. The vegetarian ham could be substituted with firm tofu or vegetarian chicken. If you have a larger slow cooker, this recipe can easily be doubled. I sometimes make enough to have for breakfast for 4 or 5 days.
