Make the sauce by pulsing the jalapeno and garlic in a food processor or blender to mince, then adding the remaining sauce ingredients and processing to combine. Set aside.
3 cloves garlic, 1 jalapeno, 1 1/2 Tablespoons maple syrup, 1 teaspoon chili powder, 1 teaspoon salt, 1/2 teaspoon cumin, 1/2 teaspoon onion powder, 1/2 teaspoon cinnamon, 1/4 teaspoon oregano, 1/4 teaspoon black pepper, Pinch of ground ginger, 1 1/2 cup chicken broth, 3/4 cup sour cream or plain Greek yogurt, 15 ounces pumpkin puree
Preheat oven to 425°F. In a large skillet, melt the butter over medium heat, then add the onion and bell pepper. Season with a little salt and pepper and sauté until soft, about 5 minutes. Add the green chilies during the last minute.
2 Tablespoons salted butter, 1/2 large sweet onion, 1 red bell pepper, 1 can diced green chilies
In a large bowl, combine the sauteed onions and peppers with the cooked, shredded chicken and 1/2 cup of the pepperjack cheese. Season with a little salt and pepper, to taste. Mix well.

Warm the tortillas for 45 seconds in the microwave until warm and pliable, then fill each tortilla with chicken mixture and roll them up. Spread 1 cup of the pumpkin enchilada sauce in the bottom of a large rectangular baking dish, then place the rolled tortillas in the sauce, seam side down. Cover with the remaining sauce and cheese, then bake for 25-30 minutes, until the cheese is melted and the enchiladas are hot.
