Prep - Preheat oven to 450°F. Line a baking sheet with parchment paper. Use a paper towel or a clean dish towel to pat dry the chickpeas. In a bowl, toss chickpeas with 1/4 cup Italian dressing and season with 1/8 teaspoon salt and pepper. Bake until crispy, about 30 minutes, stirring once halfway through.
Combine - In a medium saucepan, bring 4 cups water and the quinoa to a boil. Reduce the heat to a simmer, cover and cook for 20 minutes, or until all the water is absorbed. Fluff with a fork. Transfer the quinoa to a large bowl and let cool completely.
Create - Add the cucumber, tomatoes, scallions, mint, and parsley to the quinoa and stir to combine. Season with salt and pepper. Stir in Italian dressing and toss to combine. Serve at room temperature on a bed of greens and top with crispy chickpeas and a lemon wedge.
