In a small bowl, combine all the ingredients for the sauce. Add in the cornflour last and use a whisk to evenly dissolve it in the liquids.
Prepare your favourite vegetables as you desire, then add the teriyaki sauce to a pan over medium heat alongside other ingredients you'd like to add (I love adding vegan 'chicken' style pieces!) . Continuously stir as the sauce begins to thicken and take off the heat after a minute.
Serve with rice or noodles, vegetables, and your favourite vegan 'chicken' chunks (I love 'The chunk' from Oumph! the most!) and sprinkle with sesame seeds and spring onions.
Notes
For this recipe I've first dusted the Oumph pieces in a little flour, then tried them crispy in a little toasted sesame oil before adding the teriyaki sauce. It creates delicious & crunchy pieces that taste fantastic alongside the vegan teriyaki sauce.
