Place the shredded cheese on top of the quesadilla and warm in a large cast iron until the cheese is starting to melt.
Meanwhile on a plate combine the avocado, tomatoes, onions, cucumber, cilantro and lime juice. Mix well.
Place the avocado mix in the middle of the melted cheese and sprinkle a little of the lime juice over it.
Serve hot.
