Combine the basil, pine nuts, Parmesan, garlic, ½ cup (120 ml) of olive oil, ricotta, salt, and pepper in a food processor and puree until blended and smooth. Set aside.
2. Step
Using a vegetable peeler, peel the zucchini, yellow squash and carrots into ribbons.
3. Step
Cut the eggplant lengthwise into thin slices, then slice in half lengthwise.
4. Step
Preheat the oven to 350°F (180°C).
5. Step
Grease a 9-inch (23 cm) tart dish with butter using a piece of parchment paper.
6. Step
Lay the puff pastry in the tart dish and delicately press it flat against the bottom and up the sides. Crimp any dough hanging over the edges and prick the bottom all over with a fork.
7. Step
Lay a piece of parchment paper over the pastry and pour the rice evenly on top. The rice helps keep the bottom of the crust from rising while baking.
8. Step
Parbake the crust for about 15 minutes, until the puff pastry starts to cook.
9. Step
Carefully lift the parchment paper to remove the rice (save for using in other recipes or discard). Increase the oven temperature to 400°F (200°C).
10. Step
Spread the ricotta pesto mixture evenly on the bottom of the tart.
11. Step
Starting from the outside, line the walls of the tart with the veggie ribbons, alternating veggies, until the entire shell is filled.
12. Step
Sprinkle the oregano on top and brush with olive oil. Season with salt and pepper to taste.
13. Step
Bake for 35-40 minutes, until the veggies are tender.
