1/4 c. balsamic vinaigrette
1/4 c. barbecue sauce
1 tsp Dijon mustard
1 lb sirloin steak, cut into 1 in. cubes
2 c. cherry tomatoes
In a large bowl whisk together the balsamic vinaigrette, barbecue sauce and Dijon mustard. Reserve 1/2 c. of the marinade for basting. Marinate steak in marinade, tossing to coat.
On four metal or soaked wood skewers thread beef and tomatoes in alternating fashion. Using a long-handled tongs rub a paper towel that’s been moistened with cooking oil over grill grates to lightly coat them.
Place skewers on grill over medium heat, cover grill and grill until beef reaches desired doneness. Or broil about 4 inches from heat for 6-9 minutes. Turn occasionally and baste with reserved marinade during last three minutes of cooking.
