Heat a grill pan over medium heat and coat with cooking spray.
Thread 2 sausage halves and 1 whole baby bell pepper onto each of 8 metal skewers.
Brush the kebabs with 1 tablespoon olive oil and grill, turning as needed and covering the pan halfway through cooking, until marked all over, about 20 minutes.
Meanwhile, bring a large saucepan of salted water to a boil.
Add the pasta and cook as the label directs.
Combine the 2 sliced baby bell peppers, the spinach, olives, garlic, basil and the remaining 2 tablespoons olive oil in a large bowl; toss to coat.
Drain the pasta and immediately transfer to the bowl with the spinach mixture; toss to combine.
Season with salt and pepper and top with the cheese.
Serve the pasta salad with the kebabs.
