The beef patty taco has been standard restaurant fare around Tucson since at least the mid-70s. A hamburger patty was folded into a tortilla and fried. Topped with cheese, lettuce, and tomato.
One of my favorite Mexican restaurants now offers their famous tacos nestled in a large lettuce leaf instead of a tortilla. I was amazed at how much I enjoyed them served that way; I didn’t miss the tortilla at all. So I’ve started experimenting with the idea at home. I modified this recipe from one in a cookbook that I photographed for Chelsie Kenyon a couple of years ago.
