You can get chorizo in fine soft slices or in thick sausage form which I use in this recipe. If you are really stuck and can’t get your hands on some chorizo for this recipe, don’t panic, you can use a little leftover cooked chicken or some sliced cooked ham as a substitute. The great thing about quesadillas is that you can really adapt them to what you have, the classic ones I normally make are with some salsa, cheese and thinly sliced red onion, simple and delicious.
