Mexican Zucchini Boats

Preheat the oven to 400 degrees F (200 degrees C). Spray the bottom of a baking dish with cooking spray.

Fill a large skillet with water and bring to a boil. Boil zucchini halves for 1 minute. Drain.

Heat the large skillet over medium-high heat. Cook and stir ground beef and onion in the hot skillet until beef is browned and crumbly 5 to 7 minutes. Add tomato sauce corn bell pepper and taco seasoning; cook and stir until bubbly.

Place zucchini halves into the prepared baking dish cut-sides up. Scoop meat mixture into the boats and sprinkle cheese on top.

Bake in the preheated oven until tender and cheese is melted about 30 minutes. Garnish with scallions.
