01 - Preheat oven to 425°F. Line a large sheet pan with parchment paper or lightly grease with cooking spray.
02 - Spread sliced kielbasa and all prepared vegetables evenly across the prepared sheet pan.
03 - In a small bowl, whisk together honey, soy sauce, minced garlic, olive oil, Dijon mustard, black pepper, smoked paprika, and salt until well combined.
04 - Drizzle the honey garlic sauce mixture evenly over the sausage and vegetables. Toss gently with tongs or spatula to ensure everything is thoroughly coated.
05 - Arrange coated ingredients back into a single even layer across the pan, avoiding overcrowding for proper caramelization.
06 - Roast in preheated oven for 23 to 25 minutes, stirring halfway through cooking time, until vegetables are tender and edges are slightly caramelized.
07 - Remove pan from oven. Sprinkle with fresh chopped parsley and serve immediately with lemon wedges on the side if desired.
