Preheat your oven to 400°F (200°C) and line a large rimmed sheet pan with parchment paper for easy cleanup.
Slice the chicken sausage into half-inch rounds and peel the sweet potato before dicing it into small half-inch cubes.
Remove the seeds from the red bell pepper and slice it into thin, uniform strips.
Place the sausage rounds, sweet potato cubes, and pepper strips onto the prepared sheet pan.
Drizzle the extra virgin olive oil over the ingredients and sprinkle evenly with garlic powder, smoked paprika, sea salt, and black pepper.
Toss everything together with your hands or tongs until thoroughly coated in oil and spices, then spread into a single layer.
Roast in the center of the oven for 25 to 30 minutes, tossing the mixture halfway through, until the sweet potatoes are fork-tender and the sausage is golden brown.
Remove from the oven and garnish with freshly chopped parsley before serving warm.
