Instructions

1. Step 1: Heat 1 tbsp olive oil in a large skillet over medium heat. Add 4 bratwurst sausages and cook for 6-8 minutes per side until golden brown and cooked through, then remove and keep warm.

3. Step 3: Stir in 3 tbsp Dijon mustard, 1 tbsp white wine vinegar, and 1/4 cup chicken broth. Cook for 3-4 minutes until the sauce thickens slightly and coats the onions.
