01 - Preheat the oven to 400°F. Line a large baking sheet with parchment paper or foil for easy cleanup.
02 - In a small bowl, whisk together olive oil, lemon juice, lemon zest, garlic, oregano, salt, and black pepper.
03 - Arrange the asparagus and cherry tomatoes on the prepared baking sheet. Drizzle with half the marinade and toss to coat. Spread into an even layer.
04 - Nestle the salmon fillets among the vegetables. Brush salmon with the remaining marinade.
05 - Roast in the oven for 15–20 minutes, or until the salmon is cooked through and flakes easily with a fork, and the vegetables are tender.
06 - Remove from oven. Sprinkle with fresh parsley and serve with lemon wedges.
