1-1/2 lb boneless sirloin steak, cut into 1/2" chunks
3 tbl red wine vinegar
2 tsp hot paprika
1 tsp salt
1 tsp pepper
1/2 tsp ground cumin
1/2 tsp ground turmeric
Combine the vinegar and seasonings in a small bowl. Put the meat in a zip-loc plastic bag, pour the marinade over it, seal the bag and squish it to coat the meat. Refrigerate 3 hrs, turning the bag occasionally.
Remove the meat from the marinade and discard the marinade. Thread the beef onto 6 10" skewers. Grill or broil 6 min. or until desired degree of doneness.
