Beef Kabobs with Horseradish Sauce

These are packed with flavour and I love the horseradish/yogurt sauce to go with them.  A fun and quick meal to make on the BBQ.  From Canadian Living/The Barbecue Collection.

2 cloves garlic
1/2 tsp coarse sea salt
4 tsp mined fresh rosemary
1 tbsp olive oil
1 tsp pepper
450 g Beef top blade flatiron grilling steak or beef flank marinating steak, cut into 1 inch cubes

Horseradish Sauce:
2 tbsp each sour cream and 2% Greek Yogurt
1 tbsp minced fresh chives
1 tbsp extra hot prepared horseradish

• On cutting board, coarsely chop garlic; sprinkle with salt.  With flat side of knife or fork, mash into paste.
• In large bowl, stir together garlic paste, rosemary, oil and pepper; toss with beef until coated.  Marinate for 30 minutes.
• Thread onto skewers.  Grill on greased grill over high heat, turning once, until desired doneness, about 7 minutes for medium rare.

Horseradish Sauce:
