Make enchilada sauce like this.
Make low carb tortillas like this. Make the version including optional gelatin.
In a large saute pan, heat oil over medium-high heat. Add the minced garlic and cook for about a minute, until fragrant.
Add chicken, 1 cup enchilada sauce (half of the total amount), chicken broth, and cilantro. Simmer for about 5 minutes.
Meanwhile, preheat the oven to 375 degrees F (190 degrees C). Grease a 9x13 baking dish.
Scoop about ¼ cup chicken mixture into the center of each tortilla. Roll up and place seam side down in the baking dish.
