Start by bringing the quinoa and vegetable broth to a boil. Once boiling, cover and simmer for 15-20 minutes until the liquid is absorbed. Let it rest for 10 minutes, then fluff with a fork and season lightly with salt.
While the quinoa cooks, toast your slivered almonds. Spread them on a baking sheet and broil for 2-3 minutes, or toast in a pan over medium heat until lightly browned. This step brings out their rich, nutty flavor.
Combine olive oil, citrus juices, garlic, mustard, maple syrup, red onion, salt, and pepper. Whisk until smooth and set aside. This homemade vinaigrette really ties all the flavors together.
Add arugula to a large bowl and toss with half of the vinaigrette. Then layer quinoa, chickpeas, orange pieces, avocado cubes, toasted almonds, and feta. Drizzle the remaining dressing on top.
Gently toss everything together so the dressing coats each ingredient evenly. Serve immediately for the freshest flavor, or chill briefly if you prefer a cooler salad.
