Ingredients:
cooking spray
4 tablespoons olive oil, divided
1 tablespoon chopped fresh rosemary
1 teaspoon kosher salt, or to taste, divided
½ teaspoon freshly ground black pepper, divided, or more to taste
1 (16 ounce) package red potatoes, cut into bite-sized chunks
1 tablespoon dried onion flakes
1 tablespoon smoked paprika
1 tablespoon dried parsley
1 tablespoon dried oregano
12 ounces fully cooked kielbasa or Polish sausage, cut into 1 1/2-inch pieces
1 (12 ounce) bag fresh green beans, trimmed
1 medium yellow bell pepper, cut into bite-sized strips
1 medium onion, cut into bite-sized pieces
Directions:
Preheat the oven to 425 degrees F (220 degrees C). Line a baking sheet with aluminum foil for easier cleanup and spray with cooking spray.
Combine 2 tablespoons olive oil, rosemary, 1/2 teaspoon salt, and 1/4 teaspoon pepper in a large bowl. Add potatoes and toss to coat. Place potatoes skin side-down on the baking sheet in a single layer.
Roast in the preheated oven until tender when pierced with a fork, 23 to 25 minutes. Remove from oven; stir.
Mix remaining olive oil, salt, pepper, onion flakes, paprika, parsley, and oregano in the same bowl. Add sausage, green beans, bell pepper, and onion; mix until well combined. Add to the baking sheet; spread in a flat layer.
Roast until vegetables are tender and potatoes and sausage pieces are browned, tossing halfway through the roasting process, 20 to 25 minutes. Serve immediately.
