8 medium zucchini (about 2 1/2 pounds), trimmed, halved lengthwise
1/2 cup (1 stick) butter
2 tablespoons fresh lemon juice
1 teaspoon lemon-pepper seasoning
1 teaspoon garlic powder
1 teaspoon dried oregano
1/4 teaspoon curry powder
1/4 cup grated Parmesan cheese
Preheat barbecue (medium heat). Score cut side of zucchini halves diagonally about 1/4 inch deep at 1-inch intervals. Melt butter with lemon juice concentrate, lemon-pepper seasoning, garlic powder, oregano, and curry powder in heavy saucepan.
Season with salt and pepper. Brush seasoned butter on cut side of zucchini. Place zucchini on grill and cook until charred on all sides and just beginning to soften, about 12 minutes. Arrange zucchini on grill, cut side up, and sprinkle with Parmesan cheese; close lid of barbecue and cook until cheese just softens, about 1 minute.
