Pour olive oil in a large pot, over medium-high heat. Sauté garlic and onions briefly, till aromatic. Add eggplant and cook down until softened and brown. Add bell pepper, yellow squash, zucchini and tomatoes to the mixture and reduce to simmer.
2. Step
Stir so the vegetables are well mixed. When the vegetables are cooked through, incorporate thyme, parsley, and basil, then remove from the heat.
3. Step
Cut zucchini in half, lengthwise, then scoop out the insides to form a boat shape. Line the bottom of the boat with sliced mozzarella, then top with the cooked ratatouille.
4. Step
Bake the boat at 400˚F (200˚C) for 15 minutes or until the boat has softened and the tops are starting to brown. Serve immediately.
5. Step
P.S. Leftover ratatouille is delicious on its own or with pasta.
