Chicken Marsala (with no wine!)

Ingredients

• 2 garlic cloves, peeled and chopped
• 1.5 cups chicken or vegetable broth
• 1/4 cup heavy cream
• 1 tsp dried thyme leaves
• 1 tbsp white vinegar
• 1.5 tbsp fresh parsley, chopped
• 4 thin cut boneless, skinless chicken breasts (or 2 large ones sliced in half to about 1/2" thick)
• 3 tbsp ghee or olive oil and butter (* I like to use ghee instead of butter here since it can reach a higher smoke point)
• 1/2 cup all purpose flour (* Use white rice or arrowroot flour for gluten free)
• 1 shallot, peeled and chopped
• 8-10 oz cremini mushrooms, sliced
• 1/2 tsp ground mustard powder (or 1 tsp of dijon)
