Leerdammer Devil-of-a-Chicken Burger

1. Preheat the barbecue or grill. 2. Put the chicken breasts between sheets of cling film, spaced apart, and use a meat mallet or rolling pin to beat them out to an even thickness (this helps them cook evenly). Place in a shallow dish and add the HP® sauce and chilli flakes, turning them to coat. Season with a little salt and pepper. 3. Cook the chicken on the barbecue or under the grill for 8-10 minutes, turning once. Make sure that the chicken is thoroughly cooked by testing the thickest part with a sharp knife – the juices should run clear. If there are any traces of pink, cook for a few more minutes and test again with a clean knife. 4. Toast the cut sides of the burger buns. Top with mixed leaves and sliced tomatoes. Arrange the chicken on top and place a slice of Leerdammer ® Toastie & Burger onto each one. Finish off with sliced red onion and dill pickle.
