Heat oil in a non-stick frypan over medium heat. Add onion, garlic and mince and cook until meat has browned, breaking up any clumps whilst cooking.
Add paprika, cayenne pepper, beans, passata, currrants and 1/2 cup water. Bring to the boil, then reduce to a simmer and continue to cook until liquid has been absorbed.
Cool slightly, add to wraps with coleslaw, fold up the base and two sides, and grill in a preheated sandwich press.
