Instructions

1. Step 1: Preheat oven to 425°F. Toss 1 diced red bell pepper, 1 diced zucchini, and 1 diced red onion with 2 tbsp olive oil, 1/2 tsp salt, and 1/4 tsp black pepper, spreading evenly on a baking sheet. Roast for 20 minutes until vegetables are tender and slightly caramelized.
2. Step 2: While vegetables roast, rinse 1 cup quinoa under cold water, then combine with 2 cups water and 1/2 tsp salt in a medium saucepan. Bring to a boil, reduce to a simmer, cover, and cook for 15 minutes until water is absorbed and quinoa is fluffy. Remove from heat and let rest covered for 5 minutes.
3. Step 3: In a small bowl, whisk together 1/4 cup fresh orange juice, 2 tbsp fresh lemon juice, 1 tbsp honey, 1 tsp Dijon mustard, and 1 tbsp olive oil until emulsified and slightly thickened.
4. Step 4: Transfer cooked quinoa to a large bowl. Add the roasted vegetables, 1/4 cup chopped fresh parsley, and 1/4 cup toasted walnuts. Pour the citrus vinaigrette over the mixture and toss gently to combine, seasoning with additional salt and pepper to taste.
