Pierogis with Cabbage and Apples

Ingredients:

• 1 16.9-ounce box frozen potato and cheese pierogis
• 2 Tbsp olive oil
• 1 small yellow onion, cut into 1 x 0.5 inch piece
• 1.5 crisp Green apples, peeled and cut into 1/2-inch pieces
• 1/4 small head cabbage, shredded (purple or green)
• 1 tablespoon apple cider vinegar
• 1/2 tsp kosher salt
• 1/2 tsp black pepper

Preparations:

1. Saute the pierogis in 1 Tbsp oil until both sides are just starting to golden.
2. Meanwhile, in another pan, heat the remaining oil over medium-high heat. Add the onion and cook, stirring occasionally, until soft, 5 to 6 minutes. 
3. Add the apple and cook for 1 minute.
4. Add the cabbage, vinegar, salt, and pepper. Cook, stirring, until the cabbage is slightly wilted but still crunchy, 2 to 3 minutes. 
5. Divide the cabbage mixture among plates. Serve with three pierogis and sour cream (optional) on the side.
