• 2 x 250 g chicken breast fillets
• 2 tbsp olive oil
• 
• 1 leek, thinly sliced
• 300 g cup mushrooms, sliced
• 2 cloves garlic, crushed
• 2 tbsp white wine vinegar
• 375 g packet fresh lasagne sheets (8 sheets)

Method

1. Place chicken on an oven tray lined with baking paper. Drizzle with half the oil.
2. Cook in a moderate oven (180C) for about 15 to 20 minutes, or until cooked. Cool. Shred chicken.
3. Meanwhile, make sauce. Whisk all ingredients in a large jug until combined.
4. Heat remaining oil in a large frying pan over a medium to high heat. Add leek, mushrooms and garlic. Cook, stirring occasionally, for about 5 minutes, or until tender. Transfer to a large bowl. Stir in chicken and vinegar. Season.
