Ingredients

Equipment

• 13 x 9-inch baking dish – Essential for even cooking and beautiful presentation.
• Large skillet or sauté pan
• Mixing bowls
• Measuring cups and spoons
• Cutting board and sharp knife
• Wooden spoon or spatula
• Oven mitts
• Optional: food processor for chopping vegetables quickly

Instructions

1. Preheat your oven to 375°F (190°C). Lightly grease your 13 x 9-inch baking dish with olive oil to prevent sticking.
2. Sauté the aromatics: Heat 2 tablespoons of olive oil in a large skillet over medium heat. Add the diced onion and cook for 5 minutes until translucent. Stir in the minced garlic and cook for another minute until fragrant.
3. Add the mixed vegetables: Toss in the chopped carrots, bell peppers, zucchini, and broccoli. Sauté for 7-8 minutes until the vegetables begin to soften but still have a slight crunch.
4. Stir in the chickpeas and tomato sauce: Add the cooked chickpeas and pour in the tomato sauce. Season with dried oregano, salt, and pepper. Let the mixture simmer gently for about 5 minutes to meld flavors.
5. Combine quinoa or rice: In a separate bowl, mix the cooked quinoa or brown rice with the vegetable mixture. This will add heartiness and texture to your entree.
6. Layer the casserole: Spread half of the vegetable mixture evenly in the baking dish. Sprinkle half of the shredded mozzarella cheese over the top. Repeat with the remaining vegetable mixture and cheese.
7. Bake uncovered for 25-30 minutes until the cheese is bubbly and golden brown on top.
8. Remove from oven and let it cool for 5 minutes. Garnish with fresh chopped basil before serving.

Tips & Variations

“Feel free to swap in seasonal vegetables like eggplant or spinach depending on what’s fresh and available. For a vegan version, substitute the mozzarella with your favorite plant-based cheese or nutritional yeast.”

Looking to add some extra flavor? Try stirring in a tablespoon of balsamic vinegar or a pinch of red pepper flakes during the sauté step.

If you want to boost the protein, consider adding cooked lentils or diced tofu. For a creamy twist, layer in some Vegan Bechamel Sauce between layers.

For a Mediterranean flair, swap tomato sauce for a rich roasted red pepper sauce and sprinkle with crumbled feta cheese instead of mozzarella. To save time, prepare the vegetable mixture a day ahead and assemble just before baking.

Serving Suggestions
