This is how I make them at home! These are dsil's favorite- with no onion and tomato and extra sour cream! lol The great thing about quesadill's is you can tailor them to your exact tastes and it is a great way to sneak some veggies into those veggie haters. Try adding some tomato, avocado, spinach, mushrooms, etc.. inside the tortilla. Great way to introduce herbs too! Try cilantro, cumin, etc here! hope you enjoy!
