Preparing the Hearty Quinoa Vegetable Medley is a simple process that even novice cooks can follow with ease. Here’s a step-by-step guide to making this nutritious dish:

1. Rinse quinoa under cold water.
   Start by rinsing the quinoa thoroughly under cold water to remove its natural coating, called saponin, which can make it taste bitter.
2. In a pot, combine quinoa and vegetable broth.
   Add the rinsed quinoa and vegetable broth (or water) to a pot. Bring the mixture to a boil over medium-high heat.
3. Simmer the quinoa.
   Once boiling, reduce the heat to low, cover the pot, and let it simmer for about 15 minutes, or until the liquid is absorbed and the quinoa is fluffy.
4. Sauté the vegetables.
   In a large skillet, heat the olive oil over medium heat. Add the chopped bell peppers and diced zucchini, sautéing them for 5-7 minutes until they start to soften.
5. Add cherry tomatoes and spinach.
   Stir in the halved cherry tomatoes and spinach, cooking until the spinach wilts and the tomatoes start to soften.
6. Combine quinoa and vegetables.
   Fluff the cooked quinoa with a fork, then mix it into the skillet with the sautéed vegetables.
7. Season and serve.
   Sprinkle the mixture with garlic powder, salt, and pepper to taste. Serve the medley warm and enjoy the delicious flavors.
