This is a German dish that Jason's family makes. It's really different, but I like different! They actually don't follow a recipe so this is one that I found on Allrecipes so that I would have something to follow.
12 pieces top round beef, pounded thin (1/4 inch thick)
1 ½ c. chopped onion
1 ½ cups chopped dill pickles (or thin pickle slices)
Nonstick cooking spray
¼ cup butter
5 T. flour
2 cans beef broth
16 ounces baby carrots
4 stalks celery, cut into 1-inch pieces
Season beef with salt and pepper. Spread each piece with 1 tsp. mustard; top with 2 T. each onion and pickles. Starting at one short side of each beef piece fold long edges over, then roll beef tightly. Secure with a toothpick.
Spray large nonstick skillet with cooking spray. Brown beef rolls in batches over medium-high heat. Remove from skillet.
In same skillet, melt butter. Add flour. Cook and stir 1 minute. Add beef broth, stirring constantly. Cook and stir until mixture thickens.
Pour half of broth mixture into slow cooker. Add carrots and celery; top with beef rolls; pour remaining broth mixture into slow cooker.
Cover; cook on LOW 8-10 hours or on HIGH 4 to 5 hours. Makes 6 to 8 servings.
