In a medium saucepan, spray oil and sauté garlic. Add chipotle chili, chili powder, cumin, broth, tomato sauce, salt, and pepper. Bring to a boil.
Reduce heat to low and simmer for 5-10 minutes. Set aside until ready to use.
Spray a baking dish with nonstick spray. Preheat oven to 400°F.
In a medium nonstick skillet, sauté garlic and scallions in olive oil over medium heat for about 3 minutes; add zucchini and cilantro, salt, and pepper to taste, and cook until all liquid evaporates, about 4-5 minutes.
Remove from heat and add 1/2 cup cheese; mix well.
Divide zucchini mixture among tortillas, roll, and place seam side down in the baking dish.
Top with enchilada sauce (may not use all) and remaining cheese, then bake until hot and cheese melts, about 20 minutes.
Serve with chopped cilantro, scallions, and optionally with reduced-fat sour cream. Enjoy!
