Prepare the rolls – If using part-baked rolls, cook them according to the package. I do mine in the air fryer for 4 minutes.
Quick-pickle the carrot – Toss the thin carrot ribbons in a container with rice vinegar, shake well, and let sit.
Prep the veggies – Slice the cucumber into ribbons (avoid the seedy core). Thinly slice the spring onion on a bias and separate the layers.
Cook the tofu – Slice the tofu into four pieces per roll. Fry in sunflower oil until golden. Near the end, add Maggi seasoning and flip to caramelize.
Assemble the sandwich – Slice the rolls, spread hoisin sauce on both sides, then layer veggies and tofu. Close it up and enjoy!
