Preheat oven to 375 degrees.
Heat 1 tablespoon olive oil in a large skillet over medium. Saute the garlic and shallot until fragrant, about 2-3 minutes. Stir in the chipotle sauce, honey, chili powder, cumin, ginger, and cayenne pepper, then toss in the mushrooms and butternut squash. Pour the can of cider beer and bring to a simmer. Reduce the heat to medium-low and cook uncovered for 20-25 minutes, or until the liquid is largely absorbed. Stir in 1/2 cup of the cheddar cheese and the kale.
Warm tortillas in the microwave under damp paper towels for 30 seconds to make more pliable.
Spoon 1/2 cup enchilada sauce in the bottom of a large casserole dish. Working one tortilla at a time, scoop 2 tablespoons of enchilada filling in the center, then roll and place seam-side down in the casserole dish. Repeat with remaining tortillas. If you have leftover filling, carefully poke it into the open sides of the tortillas.
Pour remaining enchilada sauce over the tortillas. Sprinkle cheese evenly on top. Bake in the preheated oven for 15-20 minutes until the cheese is bubbly and golden. Garnish with avocado, cilantro, and sour cream or Greek yogurt, as desired.
