Heat the EVOO in a large skillet, one turn of the pan, over medium-high heat. Brown the chorizo for 2 minutes, then add the pork and brown and crumble it, 3-4 minutes. Add onion and garlic. Season the mixture with allspice, paprika, coriander, salt and pepper. Cook for 5 minutes, then add the sugar and Worcestershire sauce and the zest and juice of one lime. Turn to distribute, then stir in stock and tomato sauce. Simmer a couple of minutes.
Split and lightly toast rolls under hot broiler. Slop the mixture into rolls, then melt the Swiss cheese over top. Scatter chopped pickles on the sammies and serve with a few plantain or exotic chips alongside.
