Bring a large pot of salted water to a boil. Add the fusilli pasta and cook according to the package directions, or until just past al dente. Drain the pasta and toss it with a little olive oil to prevent sticking. Let it cool to room temperature.
In a small bowl or jar, whisk together the extra-virgin olive oil, fresh lemon juice, Dijon mustard, minced garlic, herbes de Provence (or Italian seasoning), red pepper flakes, and sea salt until well combined and emulsified.
In a large mixing bowl, add the cooled pasta, halved cherry tomatoes, cooked chickpeas, arugula, sliced cucumbers, crumbled feta cheese, torn basil leaves, minced parsley, chopped mint, and toasted pine nuts.
Pour the dressing over the salad ingredients. Gently toss everything together with salad tongs or a large spoon until the pasta and vegetables are evenly coated.
Taste the salad and adjust the seasoning as needed. Add more lemon juice, salt, pepper, or a drizzle of olive oil to suit your preference.
For the best flavor, let the salad rest for 15–30 minutes before serving. This allows the pasta to absorb the dressing and the flavors to meld together.
Transfer the pasta salad to a serving bowl or platter. Garnish with extra pine nuts, fresh basil, and a sprinkle of feta cheese. Serve chilled or at room temperature.
