In a large skillet, cook Chicken until browned and cooked through. Remove from skillet and slice.
In the same skillet, sauté Vegetables, including Garlic, until softened, about 7 minutes.
To make the Sauce, melt Butter in the skillet. Whisk in Flour and cook for 1 minute to create a roux.
Gradually whisk in Chicken broth until smooth. Bring to a simmer.
