Ingredients

• 1 medium eggplant
• 1 medium zucchini
• 2 cups tomatoes
• 1/2 red onion
• 2 cloves garlic
• 3 tbsp olive oil
• 1 tsp dried thyme
• 1/2 tsp salt
• 1/4 tsp black pepper

Instructions

1. Step 1: Preheat oven to 375°F. Cut 1 medium eggplant and 1 medium zucchini into 1/4-inch thick slices, then arrange in a single layer on a baking sheet. Drizzle with 2 tbsp olive oil, sprinkle with 1/4 tsp salt, and toss to coat evenly.
2. Step 2: Roast vegetables for 20 minutes until tender and golden at the edges, flipping halfway through. While they roast, dice 1/2 red onion and mince 2 garlic cloves.
3. Step 3: In a large oven-safe skillet, heat 1 tbsp olive oil over medium heat. Add diced onion and cook for 5 minutes until translucent, then add minced garlic and cook for 1 minute until fragrant.
4. Step 4: Stir in 2 cups diced tomatoes, 1 tsp dried thyme, 1/4 tsp salt, and 1/4 tsp black pepper. Simmer for 8 minutes until tomatoes break down slightly.
5. Step 5: Layer roasted eggplant and zucchini over the tomato mixture in the skillet, pressing gently to compact. Cover with foil and bake for 25 minutes until bubbly and heated through.
