Prepare Your Baking Trays: Start by lining two medium trays with parchment paper to make clean-up easier after roasting your veggies and chickpeas.
Cook the Quinoa Perfectly: For fluffy quinoa, use a 1:2 ratio of quinoa to water; combine 3/4 cup quinoa with 1 1/2 cups water and a pinch of salt in a pot over high heat until boiling. Reduce to medium-low heat, partially cover, and let it cook for about 10-12 minutes until all water is absorbed. Keep covered for another 10 minutes to steam.
Roast Your Vegetables and Chickpeas: Arrange quartered peppers, onion wedges, and drained chickpeas on prepared sheet pans. Drizzle with olive oil and sprinkle kosher salt before tossing together.
Prepare the Dressing: In a large jar or bowl, combine all dressing ingredients including olive oil, lemon juice, honey, spices, and herbs; whisk until blended smoothly.
Assemble Your Salad: Once cooked, combine quinoa, veggies, and fresh herbs in a large bowl; pour half of the dressing over top and toss gently to incorporate flavors.
