This is something I threw together once out of my pantry and it has become a very regular addition to my meal rotation.Lettuce, and tortilla chips are approximate, use as much as you like. You can add whatever you like for toppings: tomatoes, avocado, black olives, jalepinos. Whatever really. Depending on what you put on them, they have the potential to be pretty healthy. Hope you love it as much as I do!
