Heat butter in a pan over medium high heat.

When hot, add the onion slices in (the onions should sizzle), and reduce heat to medium to avoid burning.

On tortillas or wraps, place the apple slices, followed by the thyme and shredded Gouda cheese. Add the caramelized onions and place the second tortilla or wrap on top.
