In a heavy based pan, heat the oil. Add the mince and cook for 5 minutes, stirring with a wooden spoon to break up any lumps. Add Tex Mex Taco Spice, water or beef stock and simmer for 20 minutes or until the sauce thickens.
In the meantime, prepare guacamole, diced tomato, lettuce and cheese to serve in taco shells.
Once the sauce has thickened, assemble tacos by spooning in mince meat sauce, pile on diced tomatoes, lettuce and guacamole and sprinkle cheese on top.
