Preheat oven to 400° F and line a baking sheet with parchment or foil.

Place bell peppers, onions, and any other veggies on the baking sheet. Drizzle with oil and season with salt, pepper, oregano, parsley, garlic powder, onion powder, and paprika, to taste. Toss to coat and then bake for 20 minutes. After 20 minutes, remove from oven, add Kielbasa, toss, and bake for 20 minutes more or until veggies are cooked through.

Meanwhile, cook rice in a pot according to the packaging.

Serve rice, Kielbasa, and veggies together and enjoy!
