Mix the cream cheese, cumin, garlic & chili flakes in a bowl until well blended.
In a skillet, brown beef pieces until warm.
Divide the following between each tortilla, layering in this order; spread a thin layer of the cream cheese mixture. Then place a lettuce leaf on each tortilla & top with beef. Sprinkle with avocado, tomatoes & cheese (reserve some for top of wrap).
Starting at one end, gently roll up each tortilla into a tight tube.
Grate remaining cheese on top of wraps.
Cook about 15 min till cheese is melted & wrap is heated.
