Step 1: Roast the Zucchini
Preheat your oven to 425°F (220°C). Toss chopped zucchini with 1 tablespoon of olive oil, salt, pepper, and optional chili flakes. Spread on a baking sheet and roast for 20–25 minutes, until golden and caramelized.
Step 2: Cook the Pasta and Peas
Boil gluten-free pasta shells in salted water until al dente. In the last minute of cooking, add the peas. Drain and rinse under cool water to stop the cooking.
Step 3: Prep the Veggies
Thinly slice the fennel bulb and roughly chop the greens. Zest and juice the lemon. Set everything aside.
Step 4: Assemble the Salad
In a large bowl, combine the cooked pasta, peas, roasted zucchini, fennel, and greens. Add lemon zest and juice, and drizzle with the remaining 2 tablespoons of olive oil.
Step 5: Toss and Serve
Season with salt and pepper to taste. Gently toss until everything is coated. Serve warm, at room temperature, or chilled.
