Cheesy Potato Soup-By Jani

3 cups chicken broth ( I use water and better than bullion chicken base)
1/2 onion chopped
1 teaspoon garlic or 2 cloves
5 or 6 red potatoes diced
1/2 pkg peas and carrots
1 pkg shredded mild cheddar cheese
3/4 cup butter
3/4 cup flour
1 quart half & half
Salt and pepper

Cut up potatoes and onion. Place in crock pot with garlic, peas and carrots and chicken broth. In sauce pan melt butter, add flour and make a paste. Turn burner to medium high and slowly add half & half constantly stirring until thick. Combine with the rest of the ingredients in crock pot. Add cheese and stir until everything is mixed well. Salt and pepper to taste.
