Mix vinegar, sugar, water on heat until the sugar dissolves and combines fully. Add the mixture to a container, followed by your shredded vegetables and close the lid.
Leave the pickled vegetables to stand for an hour. If you're making this the day before, wait for the mixture to cool down and store it overnight in the fridge.
Make your mushroom pate - chop mushrooms, chives and walnuts.
To a pan, add olive oil and add mushrooms. Wait until they are cooked and release water. Let 1/2 of the water evaporate.
Add your chives, chopped walnuts, followed by your seasonings. Mix them all together in the heat until they are well combined without much water in the mixture.
Add these to your food processor and blend until it becomes a smooth paste.
Make your marinade for soy glazed 'chicken'. Defrost your vegan 'meat' and smash them with your hands. Fry them on a pan on both sides.
Pour your marinade over, followed by the corn starch slurry. Mix them until the mixture thickens.
Slice the baguette into half. Layer with 2 spoonfuls of pate, vegan mayo and sriracha. Top with vegan soy glazed 'chicken', pickled veggies, coriander and red chilies. Serve!
