American Dishes- Comforting but healthy and fast Chicken and Dumplings

I made a quick crockpot Chicken and Dumplings recipe.  It was so delicious.  This is the "healthy" version and loaded with flavor.

Healthy Crockpot Chicken

4 flash frozen breasts of chicken OR regular chicken breasts
1 onion, chopped
2 cloves of garlic, chopped
2 stalks of celery, sliced
4 carrots, sliced
1 pkg of sliced mushrooms OR a pound of mushrooms, sliced
1 red pepper, julienned
4 cups of chicken stock
3 sprigs of thyme
1 bay leaf
1/4 tsp of cayenne pepper (optional for a warmth)

1 cup of milk mixed with 3 tablspeoons of corn starch.  (or more if you like it very thick)
1 tbsp of vinegar
Salt/Pepper to taste (the red pepper and carrots will sweeten the soup considerably)
Biscuit dough, your choice. See below for ideas 

Throw all ingredients except the milk, vinegar etc to the crockpot.  Cover and cook on high for 4 hours or low for 8.  When done, take lid off, turn on high.  Remove chicken with a slotted spoon.  If you spot the bay leaf, remove that as well  Shred/slice chicken into bite sized chunks.  Add milk mixture, vinegar and stir through.  Then taste for salt/pepper and season to taste. Add back in the chicken and stir.  Then add bite sized pieces of bicuit dough all over the surface of the bubbling stew.  Put them in a single layer and then cover.  Leave for an additional 30 minutes on high.  Don't check and don't lift lid.

Serve with a cold crisp salad alongside.

Biscuits notes:  I used Trader Joe's Multigrain Baking mix.  I followed the recipe for biscuits, added a tsp of fresh thyme leaves, 1/4 tsp of pepper to it for a complementary flavor to the stew. You can use refrigerated bicuits or make homemade.  All works well with this stew.
