Preparation:
Thoroughly combine first 6 ingredients in medium bowl. Shape beef mixture into 8 1-inch thick patties.
Cover and chill at least 1 hour or up to 8 hours. Prepare barbecue (medium-high heat).
Place burgers on grill. Cover grill and cook burgers to desired doneness, about 4 minutes for medium rare.

Note: Nonfat yogurt works as well as sour cream, makes the flavor tangier. |
