Mustard-Dill Burgers

    3 tablespoons sour cream
    3 tablespoons Dijon mustard
    1 1/2 tablespoons chopped fresh dill
    10 ounces lean ground beef

    2 hamburger buns, split
    2 tomato slices
    2 Bibb lettuce leaves

Prepare barbecue (medium-high heat). Mix first 3 ingredients in
medium bowl. Transfer 3 tablespoons sauce to small bowl and reserve.
Add meat to remaining sauce in medium bowl and mix gently. Divide
meat mixture into 2 equal portions. Flatten each to 1/2-inch-thick
patty; sprinkle with salt and pepper.

Grill cut side of buns until toasted, about 1 minute. Grill patties
to desired doneness, about 4 minutes per side for medium. Spread
bottom half of buns with reserved sauce. Top each with burger, tomato
slice, lettuce and bun top.
