- 1 lemon, juiced
- 2 t water
- 1/2 cup vegetable oil
- Salt, to taste

Preheat the oven to 200°C. Melt 1 T butter in a large frying pan over a medium heat. Add the onion and fry until golden, then remove from the pan. Melt the remaining butter in the same pan over a medium heat and fry the mushrooms until golden.
Mix the harissa paste and olive oil and coat the chicken breasts in the mixture. Heat a grill pan over a high heat. Chargrill the chicken breasts for 3 minutes on each side. Transfer to a baking tray, brush with any remaining harissa mixture and finish in the oven for 5 to 7 minutes, or until cooked through but still succulent and tender. Slice diagonally.
Slice the baguette into quarters, then slice open each quarter. Fry, cut-side down, in hot oil until golden and toasted.
Assemble the burger by layering the aïoli, fried onions, sliced chicken breast, fried mushrooms and a spoonful of pineapple relish between two toasted baguette slices. Serve with the vegetable crisps.
To make the aïoli, blend the garlic, egg, egg yolk, lemon juice and water. While blending, slowly pour in the vegetable oil in a steady stream. Season to taste.
To make the vegetable crisps, heat the oil in a large saucepan. Carefully drop batches of first the beetroot, then the parsnips and sweet potato into the hot oil and fry for 1 to 2 minutes, until golden and crisp. Remove using a slotted spoon and drain on kitchen paper. Season.
