Slow Cooker Sweet and Sour Kielbasa

Ingredients

• 6 tablespoons butter
• 2 large onions, sliced
• 1 cup packed brown sugar
• 1/2 (28 ounce) bottle ketchup
• 3 tablespoons cider vinegar
• 1 1/2 teaspoons spicy brown mustard
• 1 tablespoon Worcestershire sauce
• 2 teaspoons hot pepper sauce
• 1 pound kielbasa sausage, cut into 1 inch pieces

Directions

Melt butter in a large skillet over medium heat. Saute onions until tender. Stir in brown sugar, ketchup, vinegar, mustard, Worcestershire sauce and pepper sauce. Simmer, stirring occasionally, for 20 minutes.

Place sausage in a slow cooker with the sauce and onions. Cook on low for 4 to 5 hours. The longer it simmers the better!
