Ingredients:

680g small Yukon Gold potatoes (1 1/2 lbs)
1 large yellow onion
454g Polish kielbasa (1 lb)
30ml olive oil (2 tbsp), divided
30ml whole grain or dijon mustard (2 tbsp)
15ml apple cider vinegar (1 tbsp)
15ml brown sugar (1 tbsp)
235ml sauerkraut, drained (1 cup)
115-140g shredded Gruyere or Swiss cheese (1/2 to 3/4 cups)
4-5 sprigs thyme
All-Purpose MSG Seasoning, to taste (or swap for salt and pepper)

Instructions:

Preheat the oven to 425°F (220°C).
Wash and scrub the potatoes, then pat them dry. Carefully slice the potatoes crosswise into thin sections, stopping just before slicing all the way through. Place the potatoes between two BBQ skewers or chopsticks to avoid slicing too far.
Place the prepared Hasselback potatoes on a sheet pan. Brush them with half of the olive oil, coating evenly. Season with salt and pepper to taste, then bake for 20 minutes or until the sliced potatoes start to fan out.
While the potatoes are roasting, slice the onion into thick slices and the kielbasa into bite-sized slices of even thickness.
After 20 minutes, remove the sheet pan with the potatoes from the oven and add the onions and kielbasa. Return to the oven and bake for another 20 minutes.
In a small dish, combine the remaining olive oil, mustard, apple cider vinegar, and brown sugar. Whisk to combine.
Remove the sheet pan from the oven and brush the onions and kielbasa with the glaze. Add the shredded cheese to the tops of the potatoes. Bake for another 5-10 minutes, or until the cheese is melted and bubbling.
To serve, drain the sauerkraut and scatter it over the kielbasa. Garnish with extra cheese and sprigs of fresh thyme. Serve immediately with any remaining glaze for dipping.

Notes:

Customize the dish by using your favorite type of sausage or cheese.
For a vegetarian option, omit the kielbasa and add extra vegetables such as bell peppers or zucchini.
Adjust the seasoning to your taste preferences by adding more or less All-Purpose MSG Seasoning, salt, or pepper.
