Vegan cashew mayo
100g cashews, soaked for 10 minutes in boiling water, drained and water discarded
30ml (2 tbsp) water
15ml (1 tbsp) Dijon mustard
juice of 1/2 lemon

1 Prepare a braai to grill the burgers over medium-high heat.

2 For the burger patties, place all of the ingredients – except the baby marrows, sunflower seeds and seasoning – in a blender and blitz until just smooth. Remove from blender and stir in the grated baby marrows and sunflower seeds. Season well to taste.

3 Divide the burger mixture into 4 and shape into patties. Grill on the braai until slightly charred, 3 – 4 minutes.

4 For the vegan cashew mayo, place all of the ingredients in a blender and blitz until smooth. Season to taste.

5 To assemble the burgers, place a dollop of mayo on each burger-bun half. Top with some lettuce, a patty, avo slices, tomato slices, red onion slices and sprouts. Close the burgers and serve with lemon wedges for squeezing.
