Potato Kielbasa Skillet

This is one of my favorite dishes.  It is my recipe as I have altered it significantly from the original recipe in Taste of Home.  To see the orginal you can find it at Taste of Home.

2 lb red potatoes, cubed
6 tbsp water
1 1/2 lb smoked kielbasa cut into 1/4 inch slices
1/2 tsp onion powder
2 tbsp olive oil
4 tbsp dark brown sugar
2 tbsp balsamic and 2 tbsp red wine vinegar
2 tbsp honey dijon mustard
1 tsp dried italian seasoning
1/2 tsp red and black pepper
2-3 C spinach
4 bacon stips ,cooked and crumbled

Place potatoes and water in a microwave safe dish.  Cover and microwave on high for 5-6 minutes or until tender; drain. In a large skillet, sautee kielbasa and onion powder for 6-8 minutes.  Add potatoes; sautee 8-15 minutes longer or until kielbasa and potatoes are lightly browned.
Combine the brown sugar, vinegars, mustard, thyme and pepper; stir into skillet.  Bring to a boil; reduce heat; simmer, uncovered for 2-3 minutes or until heated through.  Add spinach (as much or as little as you want) and bacon.  Cook and stir until spinach is wilted.
