Cut the zucchini in half lengthwise and then into approximately 2" pieces (about 3 pieces).
Use a spoon to scrape out the inside of the zucchini leaving a ¼" shell. (see note)
Cut each into half or thirds so you have rectangles about 1" x 2".
Brush both sides of the zucchini with olive oil and sprinkle with salt, pepper and garlic powder.
Place the zucchini skin side up and cook at 400°F for 4 minutes.
Flip the zucchini over and sprinkle with cheese and bacon bits. Cook an additional 2-3 minutes or until cheese is melted and zucchini is tender crisp. Do not overcook.
Cool 2 minutes, sprinkle with green onions and serve.
Notes
The insides of the zucchini can be saved and added to pasta sauce, soups or stews.Cook time may vary, cook just until zucchini is tender crisp.
