Ingredients

Instructions

  1. Step 1: Preheat oven to 375°F (190°C). Slice eggplant, zucchini, and yellow squash into 1/4-inch thick rounds. Finely chop bell pepper and onion, and mince garlic.
  2. Step 2: Heat 2 tbsp olive oil in a large ovenproof skillet over medium heat. Add onions and bell pepper, sauté for 5 minutes until softened, then add garlic and oregano. Cook for 1 minute until fragrant.
  3. Step 3: Stir in diced tomatoes, salt, and black pepper. Simmer for 3 minutes until liquid reduces slightly, then spread mixture evenly in the skillet.
  4. Step 4: Arrange vegetable slices in a tight overlapping pattern over the tomato base, overlapping each layer by 1/3. Brush with remaining 2 tbsp olive oil.
  5. Step 5: Sprinkle with 2 tbsp chopped basil and bake uncovered for 40-45 minutes until vegetables are tender and edges are golden brown.
  6. Step 6: Let rest for 10 minutes before slicing. Garnish with remaining basil just before serving.
