Mexican lasagna coming soon

So we are having a Cinco de Mayo themed pot luck next week at the office.  A number of ideas came to mind but one stuck out.  Do any of you remember Mexican Hot Dish from the school cafeteria growing up?  Personally, I can still taste it.  The taco meat, cheese, and soft tortillas just coming together in glorious casserole form, ah delicious.  Not quite sure how it will go down when we put our spin on it.  I can assure you it will sizzle with freshness.
