Ingredients

Instructions

  1. Step 1: Heat 2 tbsp olive oil in a large ovenproof skillet over medium-high heat. Sauté onion, garlic, and bell pepper for 3 minutes until softened. Add eggplant and zucchini; cook for 5 minutes until slightly browned.
  2. Step 2: Stir in diced tomatoes, oregano, salt, and pepper. Cook for 2 minutes until tomatoes begin to break down. Add sliced yellow squash and top with fresh basil.
  3. Step 3: Cover skillet with a lid and transfer to a preheated 375°F (190°C) oven. Bake for 25-30 minutes until vegetables are tender and sauce has thickened.
  4. Step 4: Remove lid and cook uncovered for 5 more minutes to evaporate excess liquid. Let rest for 10 minutes before serving to allow flavors to meld.
