Ingredients

• 2 cups zucchini, sliced
• 2 cups bell peppers, chopped (mix of red, yellow, green)
• 1 cup cherry tomatoes, halved
• 1 cup mushrooms, sliced
• 1 cup fresh spinach, roughly chopped
• 1 medium onion, finely chopped
• 3 cloves garlic, minced
• 1 cup cooked quinoa or brown rice (optional for added texture and protein)
• 1 cup shredded plant-based cheese (optional)
• 1 cup unsweetened almond milk or other plant milk
• 2 tablespoons olive oil or avocado oil
• 1 teaspoon dried oregano
• 1 teaspoon dried basil
• Salt and pepper to taste
• 2 tablespoons nutritional yeast (for a cheesy flavor, optional)
• 1 tablespoon lemon juice (to brighten flavor)

Equipment

• Oven-safe casserole dish (approx. 9×13 inches)
• Large mixing bowl for combining ingredients
• Knife and cutting board for chopping vegetables
• Frying pan or skillet for sautéing vegetables
• Measuring cups and spoons
• Wooden spoon or spatula
• Aluminum foil (optional, for covering during baking)

Instructions

1. Preheat your oven to 375°F (190°C). Lightly grease your casserole dish with a bit of olive oil to prevent sticking.
2. Prepare the vegetables: Wash and chop zucchini, bell peppers, mushrooms, and spinach. Halve the cherry tomatoes and finely chop the onion and garlic.
3. In a large skillet, heat the 2 tablespoons of olive oil over medium heat. Add the chopped onion and sauté for about 3-4 minutes until translucent.
4. Add the garlic to the skillet and cook for another 1 minute until fragrant.
5. Add zucchini, bell peppers, and mushrooms to the skillet. Cook for 5-7 minutes, stirring occasionally, until the vegetables start to soften.
6. Stir in the spinach and cherry tomatoes and cook for another 2 minutes until the spinach wilts slightly.
7. Transfer the sautéed vegetables to the large mixing bowl. Add cooked quinoa or brown rice if using, plant-based cheese (if desired), nutritional yeast, dried oregano, basil, lemon juice, and almond milk.
8. Season with salt and pepper to taste. Mix everything thoroughly so the flavors combine well.
9. Pour the vegetable mixture into the prepared casserole dish and spread it evenly.
10. Cover the casserole dish with foil and bake in the preheated oven for 25 minutes.
11. Remove the foil and bake for an additional 10-15 minutes until the top is lightly browned and the casserole is bubbling.
12. Let the casserole cool for about 5 minutes before serving. This helps it set and makes it easier to portion.
