Heat a non-stick frying pan, and fry the mince and onion with some seasoning until brown and cooked through, about 5 mins. Drain off the excess fat. Add the cumin, smoked paprika, sugar, vinegar and passata. Cook for 10 mins on a medium heat, then season to taste.
Mix the pineapple, onion and coriander together. Heat the tacos following pack instructions. Serve the mince in the taco shells with the salsa, Tabasco, and soured cream, if you like.
