Preheat your oven to 375°F.
In a large skillet, heat the olive oil over medium heat. Add the diced onions and sauté until they are translucent, about 3-4 minutes.
Stir in the shredded chicken, mole sauce, ground cumin, garlic powder, salt, and pepper. Cook for another 5 minutes until everything is heated through.
In a separate pan, warm the corn tortillas over low heat for about 30 seconds on each side to make them pliable.
Spread a thin layer of mole sauce on the bottom of a 9x13-inch baking dish.
Take a tortilla, fill it with about 1/4 cup of the chicken mixture, and roll it up tightly. Place it seam-side down in the baking dish. Repeat with the remaining tortillas and filling.
Once all the enchiladas are in the dish, pour any remaining mole sauce over the top and sprinkle with shredded cheese.
Cover the dish with aluminum foil and bake for 20 minutes. Remove the foil and bake for an additional 10 minutes, or until the cheese is bubbly and golden.
Remove from the oven and let cool for a few minutes. Garnish with chopped cilantro before serving.
