Preheat oven to 375°F. Spray a 7×11-inch baking dish with nonstick spray; set aside.

Heat a large nonstick skillet over medium-high heat. Swirl in 1 tspn of the oil, then add the turkey, half of the onions, half of the garlic, and 1/4 tspn of salt. Cook until browned, about 8 mins.

Meanwhile, heat a medium nonstick saucepan over medium heat. Swirl in remaining oil, then add remaining onions, garlic, 1/4 tspn salt, the oregano, and cumin. Cook, stirring occasionally, until well softened, aabout 8 mins. Stir in enchilada sauce, green chiles, and vinegar; bring to a boil. Reduce heat and simmer, covered, until the flavors are blended, about 10 mins. Remove from heat and stir in cilantro.
