Coarsely chop the turkey meat and pulse process in a food processor into a fine chop.
Heat a large, deep skillet over medium to medium-high heat with the EVOO, a couple turns of the pan. Add the bacon and render until crispy. Add the garlic, chiles and onions. Season with cumin and some pepper. Saute until tender, about 10 minutes. Add the turkey, cilantro, tomatoes and lime juice. Then add the gravy or stock to moisten. Warm through and season with salt. Remove from the heat.
Char the tortillas and blister in a hot dry skillet or over an open flame on a gas burner, 30 to 40 seconds per side.
In a sauce pot over medium heat, melt the butter. Then whisk in the flour and cook for 1 minute. Whisk in the milk, and season with salt and pepper. Cook the mixture until it thickens and coats the back of a spoon. Stir in two-thirds of the cheese to melt, then stir in the green chiles.
Fill the tortillas with the turkey and bacon mixture and arrange in a large baking dish. Pour the sauce evenly over the enchiladas. Then top with the remaining cheese. Cool and store for a make-ahead meal.
To bake the enchiladas, bring to room temperature and preheat the oven to 400 degrees F. Bake the enchiladas until brown and bubbly, about 40 minutes if from the fridge, or 20 to 25 minutes if still warm from the initial preparation.
Serve and top the enchiladas with lettuce, avocado, lime, tomatoes, onions and creme fraiche.
