Creating Mustard Hasselback Kielbasa Bites is simple when you follow these steps:

1. Preheat Oven: Preheat your oven to 400°F (200°C) and line a baking sheet with parchment paper.
2. Prepare Kielbasa: Place the kielbasa slices on a cutting board. Using a sharp knife, make several cuts along the top of each slice, taking care not to cut all the way through. This will create the Hasselback effect.
3. Make the Mustard Mixture: In a small bowl, combine Dijon mustard, whole grain mustard, honey, olive oil, garlic powder, and smoked paprika. Mix well.
4. Coat Kielbasa: Brush the mustard mixture generously over each sliced kielbasa piece, ensuring the mixture seeps into the cuts.
5. Arrange on Baking Sheet: Place the coated kielbasa slices on the prepared baking sheet, making sure they are spaced evenly.
6. Bake: Bake in the preheated oven for 20-25 minutes, or until the kielbasa is heated through and slightly caramelized on the edges.
7. Garnish: Remove from the oven and sprinkle with chopped parsley for a fresh finish.
8. Serve: Transfer the bites to a serving platter and enjoy hot.

These straightforward steps will guide you to creating these incredible bites effortlessly.
