“To make the pesto, first soak the sundried tomatoes overnight. Alternatively, if you’re short of time, put them in a saucepan, cover with hot water, bring to the boil and simmer for 10 minutes until softened. Drain, then gently squeeze until dry.
“Add all the pesto ingredients, except the mushrooms, into a food processor with a pinch of salt and whizz until smooth. Don’t over blend – you want the pesto a little chunky so there is a little bite to it. Put half of the pesto into a mixing bowl and add the mushrooms. Mix well until the mushrooms are evenly coated in pesto.
“Skewer the mushrooms onto metal skewers, or bamboo skewers soaked in water. Put the mushrooms on a hot part of the barbecue and cook, turning regularly, until they start to char and smell amazing, probably about 5-7 minutes. Carefully remove from the skewers.
“Toast the giant baps. Add some vegan coleslaw and a few rocket leaves, then top with a decent portion of the pesto mushrooms. Add a couple of slices of avocado and top with the bap lid.”
“Preheat the oven to 180oC, gas mark 4. Put the whole garlic clove into a small roasting tin and cook for 10 minutes until it starts to smell fantastic, then remove from the oven and peel.
“To make the mayonnaise, blend the roasted garlic, mustard, pepper, and soya milk with a pinch of salt until smooth. Next slowly and gently pour in the sunflower oil, with the blender running. Continue to blend until it starts to emulsify into a mayonnaise-like texture.
“Grate the red cabbage, white cabbage and carrot. Finely chop the onion and mix all together in a large bowl. Add in all the mayonnaise et voila! Coleslaw ready to go!”
