Bring a large pot of water to a boil. Add the pasta and cook according to the package instructions (until al dente). Drain and rinse with cold water.
Meanwhile, add all of the chimichurri ingredients to a food processor or blender. Pulse until combined. Taste and adjust the seasonings as needed. Set aside.
To assemble, add the pasta, roasted peppers, chickpeas, arugula and feta to a large salad bowl. Top with the chimichurri and toss until combined.
Serve at room temperature or chilled.

Notes
This can be prepped ahead of time. I would just wait to add the arugula until you are ready to serve so that it doesn't wilt.
