Cut each zucchini in half lengthwise. Cut a thin slice off the bottoms so that each half sits flat. Scoop out the pulp, leaving a 1/4-inch shell. Chop the pulp.
Heat oil in a large skillet over medium-high heat. Add beef, tomato, scallions, chili powder, cumin, 1/2 teaspoon salt and garlic powder. Cook, breaking the beef into small pieces, until no longer pink, 5 to 6 minutes. Stir in the chopped pulp.
Meanwhile, place the prepared zucchini halves in a microwave-safe dish; sprinkle with the remaining 1/4 teaspoon salt and pepper. Cover and microwave on High until tender-crisp, 2 to 3 minutes. Uncover.
Position rack in the upper third of the oven. Preheat broiler to high. Place the zucchini halves on a baking sheet. Divide the beef filling among the zucchini halves and sprinkle each half with 2 tablespoons cheese. Broil until the cheese is melted, about 2 minutes. Serve with lettuce, avocado and pico de gallo, if desired.
