Preheat your oven to 400°F (200°C) and line a large baking sheet with parchment paper for easy cleanup.
Slice the red bell pepper, green bell pepper, and red onion into thin, even strips.
Place the vegetables on the baking sheet, drizzle with extra virgin olive oil, and sprinkle with sea salt, black pepper, garlic powder, and dried oregano.
Toss the vegetables thoroughly to ensure even coating, then spread them out in a single layer.
Roast the vegetables in the oven for 15-20 minutes until they are tender and slightly charred at the edges.
While the vegetables roast, slice the chicken sausage into 1/2-inch thick rounds.
Heat a non-stick skillet over medium-high heat and add the sausage rounds in a single layer.
Sear the sausage for 3-4 minutes per side until they develop a golden-brown, crispy exterior.
Remove the roasted vegetables from the oven and toss them with the crispy chicken sausage before serving warm.
