Steak Skewers with Blue Cheese dipping sauce

Put these on the grill and simmer the sauce while the meat cooks.  We like to serve these with rice or grilled potatoes and a spinach salad!  Enjoy.

2 1/2 lb London broil, cubed
1/4 c. olive oil
1/8 c. red wine vinegar
1/2 tsp pepper
Sauce:
1/4 c. blue cheese
1 c. heavy cream
1/4 tsp pepper

Thaw in refrigerator.  Heat grill to medium and put meat on skewers.  Grill, turning occasionally, about 10 minutes or until beef is done to your liking.  Discard remaining marinade.  Meanwhile, heat the sauce ingredients over medium heat.  Simmer gently until cream reduces and thickens into a velvety sauce.  Serve as a dipping sauce with the steak.
