Roasted Vegetable and Quinoa Salad

Ingredients:

• 1 cup quinoa
• 2 cups water
• 1/2 cup olive oil
• 1/4 cup lemon juice
• 1 tsp. Dijon mustard
• Salt and pepper, to taste
• 1 red bell pepper, chopped
• 1 yellow bell pepper, chopped

• 1 cup cherry tomatoes, halved

Instructions:

1. Preheat your oven to 400°F (200°C).
2. Rinse the quinoa in a fine mesh sieve and add it to a saucepan with the water. Bring to a boil, then reduce the heat to low and simmer, covered, for 15 minutes or until the water is absorbed. Fluff the quinoa with a fork and set it aside to cool.
3. In a small bowl, whisk together the olive oil, lemon juice, and Dijon mustard. Season with salt and pepper.
4. Spread the chopped vegetables out on a large baking sheet and drizzle with the dressing. Toss to coat evenly.
5. Roast the vegetables in the preheated oven for 20-25 minutes or until they are tender and starting to brown at the edges.
6. In a large serving bowl, combine the cooked quinoa and roasted vegetables. Toss gently to combine. Serve immediately, or refrigerate until ready to serve. Enjoy!

This salad is full of colorful and nutritious vegetables, and the quinoa adds protein and fiber to make it a satisfying and healthy party dish. You can also customize it with your favorite vegetables or add some chopped nuts or seeds for extra crunch.
