  • 6 (312g) Quorn Vegan Fillets
  • 180ml vegan mayonnaise
  • 2 Tbsp nutritional yeast
  • 4 tsp lemon juice
  • 1 Tbsp wholegrain mustard
  • 1 Tbsp vegan soy sauce
  • 1 Tbsp maple syrup
  • 1 clove garlic, chopped
  • 1 Tbsp (15ml) olive oil
  • 6 burger rolls
  • 120g white vegan cheese, sliced
  • 100g cos lettuce
  • 2 (450g) large avocadoes, sliced
  • 1 (120g) medium red onion, thinly sliced


  1. For the Caesar sauce, combine the vegan mayonnaise, nutritional yeast, lemon juice, mustard, soy sauce, maple syrup and garlic. Using a hand blender, blend until smooth.
  2. Heat a griddle pan until smoking hot. Brush the Quorn Vegan Fillets with the olive oil and grill until charred and cooked through, 3-4 minutes per side.
  3. Cut each burger bun in half and grill the cut-sides of each bun in the same griddle pan until crisp and charred, 1 minute.
  4. Spread some Caesar sauce onto the base of each crisp burger bun. Top it with the sliced cheese, cos lettuce, avocado slices, grilled fillets and sliced onions. Top each burger with the top halves of the burger buns.

TIP: The chicken-style fillets can easily be replaced with Quorn Hot and Spicy Crumbed Burger patties for a spicier alternative.
