My family loves B.L.A.T. sandwiches. The addition of avocado to the normal bacon, lettuce and tomato sandwich makes so much sense to a girl born in California! We have been calling these 'BLATS' for years. Recently we decided to update our favorite treat by using a tortilla in place of the bread, and Ranch dressing instead of mayonnaise. This recipe is so easy and tasty, the hardest part is cooking the bacon!
