Ingredients

• 2 cups cooked quinoa (or any gluten-free grain like rice or millet)
• 1 medium zucchini, diced
• 1 red bell pepper, diced
• 1 cup broccoli florets, chopped
• 1 cup canned chickpeas, drained and rinsed
• 1 small onion, finely chopped
• 3 cloves garlic, minced
• 1 cup shredded mozzarella cheese (or dairy-free alternative)
• 1/2 cup grated Parmesan cheese (optional)
• 1 cup tomato sauce (make sure gluten-free)
• 1/2 cup plain Greek yogurt or plant-based yogurt
• 2 tbsp olive oil
• 1 tsp dried oregano
• 1 tsp dried basil
• Salt and pepper to taste
• Fresh parsley for garnish (optional)

Equipment

• Large mixing bowl
• Cutting board and knife
• Large skillet or sauté pan
• Wooden spoon or spatula
• 9×13 inch casserole dish
• Measuring cups and spoons
• Oven mitts

Instructions

1. Preheat your oven to 375°F (190°C). Lightly grease your casserole dish with olive oil or non-stick spray to prevent sticking.
2. Cook quinoa according to package instructions if you haven’t prepared it beforehand. Set aside to cool slightly.
3. Prepare the vegetables: Dice the zucchini, red bell pepper, chop the broccoli into small florets, finely chop the onion, and mince the garlic.
4. Heat olive oil in a large skillet over medium heat. Add the onion and garlic, sautéing until translucent and fragrant, about 3-4 minutes.
5. Add the diced zucchini, red bell pepper, and broccoli florets to the skillet. Cook for 5-7 minutes, stirring occasionally, until veggies are tender but still crisp.
6. Stir in the chickpeas, dried oregano, dried basil, salt, and pepper. Cook for an additional 2 minutes to combine flavors.
7. In a large mixing bowl, combine the cooked quinoa, sautéed vegetables and chickpeas, tomato sauce, and Greek yogurt. Mix thoroughly to blend all ingredients evenly.
8. Fold in half of the shredded mozzarella cheese and Parmesan if using. This will help bind the casserole as it bakes.
9. Transfer the mixture to your prepared casserole dish, spreading it evenly. Sprinkle the remaining mozzarella cheese on top for a golden, cheesy crust.
10. Bake uncovered for 25-30 minutes, or until the cheese is melted and bubbly, and the casserole is heated through.
11. Remove from oven and let cool for 5 minutes. Garnish with fresh parsley before serving for a pop of color and freshness.

Tips & Variations

For a vegan twist, substitute the cheese with your favorite plant-based alternatives and use coconut yogurt instead of Greek yogurt.

Feel free to swap quinoa with gluten-free rice or millet depending on what you have on hand. You can also add other seasonal vegetables like spinach, mushrooms, or carrots for extra nutrition and flavor.

If you like a bit of spice, add a pinch of red pepper flakes or some chopped jalapeños to the sautéed vegetables. For a creamier texture, stir in some ricotta or cream cheese into the filling before baking.

To make this casserole even more filling, consider adding cooked lentils or your favorite beans. And for those who love texture, topping the casserole with gluten-free breadcrumbs or crushed nuts before baking adds a delightful crunch.
