Add garlic, and when fragrant, add a little salt & pepper - stir well

Add broth a cup at a time stirring well to make sure it’s smooth
Add the thyme and cooked chicken bring to a simmer & cook until thickened and heated though, about 10 minutes

Add the milk and mix until just enough for it to come together to a loose wet dough
Drop spoonfuls (about a tablespoon and a half) on top of the chicken mixture but keeping them from touching too much, bring to a slow simmer and put on the lid cook about 10 minutes
