Preheat oven to 350°. Score zucchini and scoop out the flesh into a bowl. Place zucchini halves in a shallow baking dish, drizzle with 1 tablespoon of the olive oil, and season with salt and pepper. Bake for 12 to 15 minutes, or until mostly tender.

In a large skillet over medium heat, heat the remaining 1 tablespoon olive oil. Add the shallot and cook until soft, about 5 minutes. Add the garlic and cook until fragrant, about 1 minute more. Add the zucchini flesh and cook until light golden, about 2 minutes. Add the chickpeas, tomatoes, olives and oregano and cook, stirring occasionally, until the mixture is heated through, about 5 minutes.

Spoon chickpea mixture into the zucchini boats, then top with feta. Bake until zucchini is just tender and cheese is melted, about 10 minutes more. Drizzle the lemon juice over the zucchini boats, and garnish with the basil and dill. Serve warm.
