Buns:

1 (11 oz.) can refrigerated breadstick dough

Filling:

1 egg
3 tbsp. dried onion flakes
2 tbsp. milk
1 tbsp. Worcestershire sauce
1/2 tsp. salt
1/8 tsp. pepper
1/2 c. plain bread crumbs
1 lb. hamburger

Heat oven to 375°F. Separate dough into 12 breadsticks. Cut each breadstick into 4 pieces; place on ungreased cookie sheet.

Bake at 375°F for 10 to 12 minutes or until lightly browned. Immediately remove from cookie sheet; place on wire racks. Cool about 5 minutes. Split each in half, keeping tops and bottoms together to form miniature buns. Reduce oven temperature to 350°F.

Beat egg in medium bowl; add onion, milk, Worcestershire sauce, salt and pepper. Stir in breadcrumbs. Add hamburger; mix well. Press mixture into thin layer in bottom of ungreased 13 x 9-inch pan.

Bake at 350°F for 14 to 16 minutes or until thoroughly cooked. Cut into 48 rectangles (8 strips crosswise and 6 strips lengthwise). Fill buns with miniature burgers. Place ketchup in a small bowl for dipping sauce.

Note: You may also use mustard as your dipping sauce.
