Preheat barbecue grill to medium.
Place croutons in a small sealable plastic bag, seal and crush with a rolling pin, leaving some larger pieces.
Pour into a large bowl. Add pork, bacon, shallot, cheese, 2 Tbsp (30 mL) dressing and Worcestershire sauce; mix with your hands until combined. Shape into four 1⁄2-inch (1 cm) thick patties.
Place patties on greased grill and grill for about 5 minutes per side or until no longer pink inside and a meat thermometer inserted horizontally into the center of a patty registers 160°F (71°C).
Spread remaining dressing over cut sides of buns. Place lettuce on bottom halves of buns and top each with a patty. Top with bacon slices and cheese. Cover with top halves of buns.
