Ingredients

• 1 cup quinoa, rinsed
• 1 1/2 cups vegetable broth
• 1 tablespoon olive oil
• 1 medium onion, diced
• 3 cloves garlic, minced
• 1 red bell pepper, chopped
• 1 zucchini, diced
• 1 cup broccoli florets
• 1 can (15 oz) black beans, drained and rinsed
• 1 cup corn kernels (fresh or frozen)
• 1 cup shredded mozzarella cheese
• 1/2 cup shredded cheddar cheese
• 1 cup plain Greek yogurt
• 1/2 cup grated Parmesan cheese
• 1 teaspoon smoked paprika
• 1 teaspoon dried oregano
• Salt and pepper to taste
• Fresh parsley for garnish (optional)

Equipment

• Medium saucepan for cooking quinoa
• Large skillet for sautéing vegetables
• 9×13-inch casserole dish
• Mixing bowl
• Wooden spoon or spatula
• Measuring cups and spoons

Instructions

1. Preheat your oven to 375°F (190°C). Lightly grease your casserole dish with olive oil or cooking spray.
2. Cook the quinoa: In a medium saucepan, combine rinsed quinoa and vegetable broth. Bring to a boil, then reduce heat to low, cover, and simmer for 15 minutes or until liquid is absorbed. Remove from heat and fluff with a fork.
3. Sauté the vegetables: While quinoa cooks, heat olive oil in a large skillet over medium heat. Add diced onion and garlic, cooking until fragrant and translucent, about 3-4 minutes.
4. Add chopped bell pepper, zucchini, and broccoli florets to the skillet. Cook for 5-7 minutes until vegetables are tender but still crisp. Season with smoked paprika, oregano, salt, and pepper.
5. Combine ingredients: In a large mixing bowl, combine cooked quinoa, sautéed vegetables, black beans, corn, Greek yogurt, half of the mozzarella and cheddar cheese, and Parmesan. Stir until everything is well mixed.
6. Transfer the mixture to the prepared casserole dish. Spread evenly with a spatula.
7. Top with the remaining mozzarella and cheddar cheese.
8. Bake for 20-25 minutes until the cheese is melted and bubbly and the casserole is heated through.
9. Remove from oven and let cool for 5 minutes. Garnish with fresh parsley if desired before serving.

• Swap the black beans for chickpeas or kidney beans to change the flavor profile.
• For a vegan version, replace the cheese with dairy-free alternatives and use coconut yogurt instead of Greek yogurt.
• Try adding a dash of hot sauce or red pepper flakes for a spicy kick.
