Bring a large pot of salted water to a boil and add the fusilli pasta. Cook according to package directions until al dente (usually 9-11 minutes), stirring occasionally to prevent sticking. Drain the pasta in a colander and immediately toss with a light coating of olive oil to prevent clumping. Spread the pasta on a large sheet pan or bowl and let it cool to room temperature for about 10-15 minutes while you prepare the remaining components.

In a small bowl, whisk together the extra virgin olive oil, fresh lemon juice, Dijon mustard, minced garlic, herbes de Provence, red pepper flakes, and sea salt. Whisk until well emulsified and taste for seasoning—the dressing should be balanced between bright, garlicky, and herbaceous. While the dressing comes together, roughly chop the fresh basil, parsley, and mint, keeping them separate so you can layer the flavors. I like to keep my fresh herbs in separate piles until the last moment so they stay vibrant and don't bruise from early mixing.

While the pasta cools, halve the cherry tomatoes and slice the cucumbers into thin half-moons. Rinse and thoroughly dry the chickpeas—this is important because excess moisture will dilute the dressing and make the salad watery. Halve the kalamata olives and roughly chop the toasted pine nuts. Keep all of these components in separate bowls until assembly so you maintain control over texture and can ensure even distribution throughout the salad.

In a large serving bowl, combine the cooled pasta from Step 1 with the prepared vegetables and proteins from Step 3: tomatoes, chickpeas, cucumbers, olives, and pine nuts. Add the arugula and crumbled feta cheese, then pour in the dressing from Step 2 and gently toss until everything is evenly coated. The combination of warm pasta and room-temperature vegetables will allow the flavors to meld beautifully without the arugula becoming too wilted. Finally, fold in the fresh herbs from Step 2, reserving a small handful of basil to scatter over the top just before serving for maximum freshness and visual appeal.

Taste the assembled salad and adjust the seasoning as needed—you may want to add a squeeze of fresh lemon juice for brightness, a pinch more sea salt for depth, or a drizzle of extra virgin olive oil for richness. Scatter the reserved fresh basil over the top and serve immediately while the pasta is still slightly warm and the vegetables are crisp. The salad is best enjoyed fresh, though it can be refrigerated for up to 2 hours if needed (bring to room temperature before serving).
