Potato and Ham Chowder

Here is my potato chowder recipe that almost everyone has, but in case you don't have it I thought I would post it. ;) My ultimate favorite winter recipe!

Ingredients:
1 package (5 ounces) Betty Crocker scallped potatoes
1 cup diced fully cooked ham (I don't add this to my chowder, but feel free to try it)
4 cups (3 cans) chicken broth
2 medium stalks (1 cup) of celery, chopped (I don't add this either)
1 medium onion (1/2 cup), chopped
1/8 teaspoon pepper
2 cups half-and-half
1/3 cup all-purpose flour

Directions:
Mix potatoes, sauce mix from potatoes, ham, broth, celery, onion and pepper in 3 1/2 to 4 quart slow cooker. (Mine comes out perfectly in this size slow cooker, but if you have a bigger one, I don't know how to change the recipe so that it comes out the right consistency. Maybe one of you guys that have made it in a bigger one can post your tips.)

Cover and cook on low heat setting 7 hours.

Mix half-and-half and flour. Gradually stir half-and-half mixture into chowder until blended.

Cover and cook on low heat setting 1 hour, stirring occasionally, until thickened and vegetables are tender.

I sprinkle grated cheddar cheese on top after dishing into a bowl or bread bowl.
