- Heat a large sauté pan over medium heat and add 3 tablespoons of olive oil. 
- Once the oil is heated, add the chopped red onion to the pan. 
- Sauté the onion until it becomes soft and translucent, which usually takes about 5 minutes. 
- Next, add 4 minced garlic cloves to the pan and cook for an additional 1 minute, stirring continuously. 
- Stir in ⅓ cup of minced chipotle peppers in adobo sauce along with the diced vine-ripened tomatoes. 
- Cook the mixture until most of the liquid from the tomatoes has evaporated and the mixture has thickened. Stir often during this process, which typically takes approximately 20 minutes. 
- Once the mixture has thickened, add 3 thinly sliced scallions, 2 tablespoons of honey or maple syrup, 1 teaspoon of salt, 1 teaspoon of pepper, and ½ cup of chopped cilantro to the pan. 
- Finally, add 2½ cups of cooked shredded chicken to the pan and mix well to combine all the ingredients. Keep the mixture warm while you prepare the quesadillas.
