3In a small mixing bowl, add half a cup of brown sugar, half a cup of apple cider, two tablespoons of Dijon mustard, a teaspoon of garlic powder, salt, pepper, and red pepper flakes.
4Whisk all the ingredients in the mixing bowl until it's combined.
5Pour the mixture on top of the apples and sausage.
