Ingredients

  • 2 cups chopped zucchini – fresh and tender
  • 1 cup diced bell peppers – for sweetness and crunch
  • 1 cup fresh spinach leaves – packed with nutrients
  • 1 cup cooked quinoa – a protein-rich grain
  • 1 cup canned chickpeas, drained and rinsed
  • 1/2 cup diced onions – for flavor depth
  • 2 cloves garlic, minced – aromatic and healthy
  • 1 cup low-fat cottage cheese or vegan ricotta – for creaminess
  • 1/2 cup shredded low-fat mozzarella or vegan cheese – melting goodness
  • 1/2 cup tomato sauce – adds moisture and zest
  • 1 teaspoon dried oregano – classic herb flavor
  • 1 teaspoon dried basil – aromatic and warm
  • Salt and pepper to taste
  • Cooking spray or olive oil for greasing the baking dish

Equipment

  • Medium mixing bowl
  • Large skillet or frying pan
  • 9×9 inch casserole dish
  • Wooden spoon or spatula
  • Measuring cups and spoons
  • Oven preheated to 375°F (190°C)

Instructions

  1. Preheat your oven to 375°F (190°C). Lightly grease your casserole dish with cooking spray or a small amount of olive oil to prevent sticking.
  2. Prepare the vegetables: In a large skillet over medium heat, add a teaspoon of olive oil. Sauté the onions and garlic until fragrant and translucent, about 3-4 minutes.
  3. Add the zucchini and bell peppers to the skillet. Cook for another 5 minutes until they begin to soften but still retain some crunch.
  4. Stir in the spinach leaves and cook until wilted, about 2 minutes. Remove the skillet from heat and set aside.
  5. In a large mixing bowl, combine the cooked quinoa, chickpeas, sautéed vegetables, tomato sauce, oregano, basil, salt, and pepper. Mix gently until all ingredients are well incorporated.
  6. Fold in the cottage cheese (or vegan ricotta) to add creaminess without excess fat.
  7. Transfer the mixture into the prepared casserole dish, spreading it evenly.
  8. Sprinkle the shredded mozzarella or vegan cheese evenly over the top.
  9. Bake for 25-30 minutes until the casserole is heated through and the cheese is melted and slightly golden.
  10. Remove from oven and let it cool for 5 minutes before serving to allow the casserole to set.

Tips & Variations

“Feel free to customize your casserole by adding your favorite vegetables or swapping the grains. Sweet potatoes, mushrooms, or kale work beautifully in these dishes!”

Swap the quinoa for brown rice, bulgur, or barley for a different texture and flavor. For added protein, toss in cooked lentils or white beans.

Make it vegan by using plant-based ricotta alternatives and vegan shredded cheese. Nutritional yeast can add a cheesy flavor boost.

For a crunchy topping, sprinkle whole wheat breadcrumbs mixed with a little olive oil and herbs before baking.
