Boil a large pot of salted water and cook the pasta until al dente, usually 8-12 minutes. Drain and rinse under cold water.

Preheat oven to 400°F (200°C). Chop seasonal vegetables and toss with olive oil, salt, and pepper. Roast for 20-25 minutes.

Prepare protein if using. Heat chicken, sausage, or chickpeas in a skillet over medium heat until warmed through, about 5-7 minutes.

In a large bowl, combine cooled pasta, roasted vegetables, and protein. Add nuts or seeds and cheese if desired.

Whisk dressing ingredients together until smooth and combine with salad, adjusting seasoning as needed.

Chill for 15-30 minutes to allow flavors to meld before serving.
