1(16 oz)tube refrigerated Pillsbury Grands Refrigerated Biscuits
Place chicken broth, cream of chicken soup, diced onions and celery into a 5-6 quart slow cooker. Stir well (it will be a bit lumpy from the cream of chicken soup.)
Add frozen chicken breasts into crock pot and season with garlic salt and pepper.
Cover and cook on low for about 4-6 hours (until chicken is fully cooked through.)
Then take the chicken out and cut it into bite size pieces or shred it with a couple of forks. Put the chicken back into the slow cooker. Add frozen vegetables into the slow cooker if you are using.
Take the biscuits and flatten each one with the palm of your hand. Then cut the biscuits into strips then cut down the center.
Put 1/2 cup flour into a bowl and place slices of biscuits into the flour and toss them to coat well with the flour.
Drop the coated biscuits (one by one into the slow cooker.) Doing this one at a time will keep them from sticking together when you drop them in. The flour is also going to help thicken the broth. Take a spoon and gently push the biscuits down under the broth so the tops get moistened (don't stir.)
Cover and cook on high for about 1 to 1 1/2 hours. Carefully take a dumpling out and check to make sure it is cooked through. If not, continue to cook until done.
Give it all a gentle stir. Sprinkle with some dried parsley (optional.) Then serve!
