Kielbasa With Pierogies & Caramelized Onions

• 3 tablespoons olive oil, divided
• 1 large yellow onion, thinly sliced
• 1 lb frozen potato and cheddar pierogies, do not thaw
• 1 lb kielbasa, sliced, any variety will work
• 2 tablespoons apple cider vinegar
• 2 tablespoons whole grain mustard
• fresh parsley, chopped for garnish (optional)

1. In a large saucepan, heat 2 T olive oil over medium heat. Add onions, stirring occasionally, until they turn a golden color, about 15-20 minutes. Spread pierogies on top of onions in a single layer. Lower heat to medium, cover pan and let cook another 5 minutes, stirring every other minute. Add sausage slices and continue to cook, stirring occasionally, until pierogies and sausage are cooked through and starting to turn golden brown.
2. Meanwhile, in a small bowl, stir together vinegar, mustard and remaining 1 T olive oil.
3. Add dressing to pan with the sausages, pierogies and onions and toss to combine. Season with salt and pepper, if needed. Place on a serving platter and garnish with parsley.
