Method:
Shred jicama on the large holes of a box grater. Working with one handful at a time, squeeze jicama firmly to remove excess liquid; discard liquid and transfer jicama to a large bowl.
Add sour cream, green onions, corn, beans, parsley, vinegar, cayenne and salt and fold together to combine. Set aside while grilling the sausages.
Preheat a grill. Grill sausages until browned and cooked through. Grill tortillas until lightly browned and softened. Wrap sausages in tortillas and serve with slaw.
