Step 1

Cut tofu crosswise, then lengthwise, to make 4 burger-size squares. Using a skewer, poke holes in the tofu, then pat dry with paper towels. Stir soy sauce, honey and ginger in a shallow dish and turn each square of tofu to coat. Set aside.

Step 2

Bring carrots, vinegar, sugar and salt to a boil in a small saucepan, then remove from heat. Stir in cucumbers. Set aside.

Step 3

Preheat barbecue to medium. Oil grill and barbecue tofu, reserving marinade, until grill marks form, 2 to 3 min per side. Return tofu to dish and turn each square to coat. Lightly toast buns on grill.

Step 4

Assemble burgers with tofu, mayo, sriracha (if desired), pickled vegetables and cilantro. Drizzle burgers with remaining marinade for extra flavour.
