Pat salmon fillets dry and brush both sides with 1/4 cup Garden Goddess dressing.
Preheat a stovetop grill pan or outdoor BBQ to medium-high heat and spray the cooking surface generously with avocado oil cooking spray.
Place the salmon fillets on the hot grill and cook undisturbed for 4 minutes.
While the salmon cooks, toss sweet peppers, mushrooms and any additional tomatoes with 2 tablespoons Garden Goddess dressing.
Grill the tossed vegetables alongside the salmon; after 4 minutes flip the salmon and continue cooking for about 5 more minutes, or until the salmon reaches 145°F (it flakes easily with a fork).
Remove salmon and vegetables from the grill and immediately drizzle lightly with additional Garden Goddess dressing.
Make the chickpea salad by combining the drained chickpeas, 3 tablespoons Garden Goddess dressing, 1/3 cup chopped dill and parsley, lemon zest, 1/2 cup diced tomatoes and minced scallions in a large bowl; toss to combine.
Serve salmon on a bed of arugula with sliced avocado, cooked quinoa and the chickpea salad. Drizzle extra dressing before serving if desired.
