Years ago I worked at a little drive inn that served the best taco burger I had ever eaten. I didn't get the recipe for their taco meat but i have made mine as close as I could get it. I still like to make these occasionally because they taste so good and bring back so many good memories.
Crumble ground chuck into a large skillet heated to medium low. I use a potato masher to break up the meat. That way there will be no large chunks of meat.
Add garlic, 1 tablespoon chopped onion and taco seasoning to the meat. Stir occasionally until the meat is done.
Add flour and combine until any excess liquid from the meat is absorbed. Add the water and combine well.
Cook until the mixture thickens a little. This will help the meat mixture hold together a little bit. You’ll understand this step once you start to eat your burger.
Place a heaping tablespoon of meat mixture on the bottom of each bun. Spread out the meat till it covers the bun. Then layer with cheese, chopped onion, lettuce, tomato and 1 crisp corn tortilla. Now place another spoonful of the meat mixture, cheese, onion, lettuce, tomato and then put the top of the bun on top of everything.
This great served with garnishes of guacamole, sour cream and your favorite salsa. Don't forget plenty of napikins...Enjoy!
