Preheat your oven to 400°F (200°C) and line a baking sheet with parchment paper.
Place the broccoli florets and chopped red bell pepper on the baking sheet, then drizzle with olive oil and sprinkle with sea salt, black pepper, and garlic powder.
Toss the vegetables to coat evenly and roast for 15-18 minutes until they are tender and slightly charred at the edges.
While the vegetables roast, bring a large pot of salted water to a boil and cook the chickpea pasta according to the package instructions until al dente.
Slice the chicken sausage into rounds and place them in a large skillet over medium-high heat, browning for 3-4 minutes per side until golden.
Drain the pasta, making sure to reserve about 2 tablespoons of the starchy pasta water.
Add the cooked pasta and roasted vegetables into the skillet with the chicken sausage.
Drizzle with lemon juice, add the fresh parsley, and toss everything together, adding the reserved pasta water if needed to help the flavors meld.
Serve immediately while hot.
