Crockpot Potato Leek Soup

Here is my debut cooking leeks.  I've always liked them, but they somehow seemed like a "fancy" ingredient.  This soup sounded really tasty, so I decided it was time to give them a try.  This soup is definitely yummy, one that my husband loved as well (he's very particular about his soups...thinks they are not a true meal).  This is yet another recipe from the Sister's Cafe, where I have gotten many tasty recipes!

6 medium potatoes, peeled and diced
2 leeks, washed, sliced, including white and light green parts
1 cup chopped onion
1 carrot, sliced
1 stalk of celery, sliced
4 cups chicken broth
1 Tb dried parsley flakes
1 tsp garlic salt
2 Tb butter
12 oz. can evaporated milk
12 oz. bacon, cooked and crumbled
sharp cheddar cheese, shredded
chives, chopped - optional

Combine everything except last 4 ingredients in crockpot. Cook on low 7-9 hours or on high 3-4 hours. Stir in the can of evaporated milk the last 45 minutes. Serve hot topped with bacon, cheddar, and chives.
