Ingredients
1 egg
2 tbsp (25 mL) water
1/4 cup (50 mL) dry bread crumbs

2 tsp (10 mL) Dijon mustard
1/2 tsp (2 mL) salt
1/2 tsp (2 mL) Worcestershire sauce

Preparation:
In bowl, beat egg and water with fork; mix in bread crumbs, onion, mustard, salt, Worcestershire and pepper. Mix in beef. Shape into four 1/2-inch (1 cm) thick patties. (Make-ahead: Cover and refrigerate for up to 6 hours. Or layer between waxed paper in airtight container and freeze for up to 1 month; thaw in refrigerator.)
Place patties on greased grill over medium-high heat; close lid and cook, turning patties once, for about 10 minutes or until no longer pink inside. Place in hamburger buns.
