There are many ways to make this recipe even healthier. You could use a low-calorie cheese in place of the cheddar or turkey bacon in place of the regular bacon. Additionally, you could use a BBQ rub in place of the sauce, but be advised that the quesadilla will be much more dry. For a twist on this recipe, substitute the apple for fresh peaches or pears or squeeze a little fresh lime juice on the finished product. I promise all of these variants are extremely good as well!
