I used to make this a couple of times a month and take it into work as part of a pot luck luncheon.   I always had to make the recipe triple to accommodate everyone.  Use your imagination and your tastes to make it.  I will tell you not to use Thousand Island dressing, I tried it, not good.

Ingredients

* 1 lb ground beef
* 1 cup chopped lettuce (more or less to your liking)
* 1 cup chopped tomato (more or less to your liking)
* 1 cup cheddar cheese (more or less to your liking)
