This salad is packed full of vitamins! The black grapes are a delicious sweet complement to the salty cheese. This is ideal for leftover chicken, but if you don’t have any, you can also use chicken thighs.
Season the chicken. Heat 2 tablespoons of olive oil in a thick-bottomed pan and fry the drumsticks so they are brown all over. Put the heat down to a low setting, add a splash of water and leave the chicken to cook for 30 minutes (you may need to add more water if the chicken gets dry). Leave it to cool and cut the meat into pieces. Cut the radicchio stalks lengthways down the middle and remove the core. Then cut them into strips. Remove the strings from the celery sticks and slice them diagonally into thin rings. Make a vinaigrette with the mustard, mayonnaise, vinegar, and a pinch of salt and pepper. Add the rest of the olive oil and beat it into a smooth dressing. In a bowl, mix the radicchio, curly endive and celery and then add the dressing. Divide this between 4 plates, put the chicken and grapes on top, sprinkle with finely chopped parsley and finish with shavings of Old Amsterdam.
