Best Ham and Navy Bean Soup

This is a really good ham and bean soup!
It's got just enough beans, fresh vegetables,
herbs and spices in it to balance out perfectly.
I like it because there's no salt added in this.

Ingredients:
1/2 pound navy beans
1 ham bone with 1 cup ham, chopped
1 celery stalk, peeled and chopped
1 medium onion, peeled and chopped
2 garlic cloves, peeled and minced
3 tomatoes, fresh chopped
2 tablespoons olive oil
1 tablespoon un-salted butter
2 carrots, peeled and chopped
1/4 cup fresh parsley, chopped
1 bay leaf
1 teaspoon dry mustard powder
1 teaspoon ground black pepper
1 teaspoon lemon juice
1/2 teaspoon brown sugar
1/2 teaspoon liquid smoke
1/2 teaspoon cayenne pepper

Directions:
Place beans in a pot and cover with water,
let soak overnight, drain and rinse beans.
Use a big soup pot, add water, ham bone, ham,
bay leaf, dry mustard, pepper, chopped carrots,
parsley, and tomatoes. With heat on medium,
let it all simmer for about 30 minutes,
stirring occasionally.
Heat a large frying pan, add olive oil and butter.
Add the chopped celery, onion, garlic,
and the liquid smoke, saute for 3 minutes.
Add the contents of the frying pan to the soup,
and stir well. Simmer on low heat for 45 minutes.
