Now chop the rest of the heads into small pieces and place in a large bowl.
Peel and chop your apple into thin julienne sticks then add to your endive in the large bowl.
In a separate bowl mix the mayonnaise, yoghurt, lemon juice and salt and pepper (taste to check that you have the right amount of lemon and seasoning to suit your taste).
Add the mayonnaise and yoghurt dressing to the endive and apple and mix well (if you are being posh you can now put the endive mixture in your pretty serving dish :) )
