Shape into 4 firm patties about 3 inches in diameter and 1 1?2 inches thick.

Set aside.Using a wide spatula, carefully place the tuna patties on the grill. Grill the patties, gently turning once, until lightly browned, about 5 minutes total for medium-rare, 8 minutes total for medium. At the same time, lightly toast the bread slices on the grill.

Transfer to individual plates.

Place the tuna patties on half of the bread slices. Top with the lettuce leaves, tomato slices and chives.

Garnish with wedges of dill pickle.
