In a medium saucepan, combine quinoa and broth. Bring to a boil, then reduce heat to low, cover, and simmer for 15 minutes or until liquid is absorbed.
Season chicken strips with oregano, garlic powder, salt, and pepper. Toss asparagus with 0.5 tablespoons of olive oil.
Preheat a grill or grill pan over medium-high heat. Cook chicken for 3-4 minutes per side until the internal temperature reaches 165°F (74°C).
Grill asparagus for 4-5 minutes, turning occasionally, until lightly charred and tender-crisp.
Prepare the dressing by whisking tahini, lemon juice, maple syrup, and the remaining 0.5 tablespoons of olive oil in a small bowl. Thin with 1 tablespoon of warm water if necessary.
Divide cooked quinoa equally among four bowls. Top with grilled chicken, asparagus, halved cherry tomatoes, and diced cucumber.
Garnish with fresh parsley and drizzle with the tahini-lemon dressing before serving.
