Walk past the fried chicken shop knowing you can make this tasty, low-fat chicken burger at homeIngredients
Heat grill to high. Place the chicken breasts between 2 pieces of cling film and sock it with a rolling pin until they turn half their original thickness.
Whizz the toast in a food processor to rough breadcrumbs, and then tip out onto a plate.
Beat the egg and mustard in a bowl and season the grilled chicken breasts.
Dip the chicken into the egg and cover it with toasty breadcrumbs.
Grill the chicken with breadcrumbs for about 10 mins, until golden and crisp on both sides and the chicken is cooked through.
Beat the lemon zest, juice and lots of black pepper into the mayonnaise. Spread some of the mayo onto the bottom halves of the buns, top with a chicken breast and salad of your choice and serve.
