Cut zucchini in half, lengthwise. Bring a large pot of water to a boil & add zucchini halves. Boil for 1 minute, remove from water & set aside to cool.
Once zucchinis are cool, hollow out with a small spoon to make "boats." Place zucchini filling in a small bowl and set aside zucchini halves.
Heat oil in a large pan. Add diced onion & green pepper. Cook for 5 minutes. Add cumin, chili powder, & minced garlic. Cook for another 1-2 minutes.
Add zucchini filling, (cooked) ground hamburger, oregano, corn, cilantro, & ½ cup enchilada sauce. Cook for 5 minutes or until all ingredients are thoroughly heated. Add salt & pepper to taste.
Pour ½ cup enchilada sauce in the bottom of a 9"x13" baking dish. Then line bottom of dish with hollow zucchini boats. Fill boats with hamburger/zucchini mixture. Pour remaining enchilada sauce on top of boats, top with shredded cheese.
Bake for 35-40 or until zucchini boats are tender.
