2. Halve the large or medium zucchini lengthwise. If using the large one, cut into 8 pieces.
3. With a spoon, remove the seeds from the zucchini and discard them. Use a small knife to remove as much of the flesh as possible from the shells, taking care not to puncture the shells. Transfer the flesh to a bowl.
4. Place the outer shells in the roasting pan with 1/4 inch of water. Bake them for 15 minutes or until they are softened but not fully cooked. Leave the oven on.
5. Chop the zucchini flesh coarsely.
6. In large skillet, heat the oil and cook the onion, stirring often, for 8 minutes or until softened. Add the turkey or beef and continue cooking, stirring, until it breaks up. Remove the skillet from the heat.
7. Add the bread crumbs, the 1/4 cup of Parmesan, salt, pepper, thyme, oregano, and lemon juice. Stir in the chopped zucchini flesh.
8. Divide the filling among the zucchini shells. Cover with tomatoes. Bake for 20 minutes.
9. Sprinkle the filling with more Parmesan cheese and continue cooking for 20 minutes or until the cheese melts and the squash is tender when pierced with a skewer. ( Total cooking time is 40 minutes.) Janet McLeod
