1 tomato, chopped
30 ml (2 tbsp) shredded Parmesan cheese
30 ml (2 tbsp) chopped fresh basil
1 clove garlic, finely minced
5 ml (1 tsp) balsamic vinegar
5 ml (1 tsp) extra-virgin olive oil, plus extra for bread
750 g (1 1/2 lbs) ground beef
15 ml (1 tbsp) burger seasoning
8 slices sourdough bread
In a small bowl, combine tomato, Parmesan cheese, basil, garlic, vinegar and 5 ml (1 tsp) olive oil. Set aside.
Gently shape ground beef into 4 patties, 1 cm (1/2 inch) thick. Season burgers on both sides with seasoning.
Grill over direct medium heat (180 to 230 C/350 to 450 F), with the lid closed as much as possible, until the internal temperature reaches 160 C (325 F) for medium, 12 to 15 minutes, turning once.
Lightly brush both sides of sourdough bread with olive oil. Grill for 3 to 4 minutes, turning once, until bread is lightly toasted. Place each burger on a slice of bread; top with tomato mixture and remaining bread slices.
Makes 4 servings.
