This is a very rich onion tart but that didn't stop my 2 year old demolishing a HUGE piece. Both kids ate really well so this definitely passes the kid-friendly test. Using phyllo can be a fiddly process because the bottom layers of the pastry want to dry out before you have a chance to fold them over. But otherwise this recipe is very easy to prepare. PS. I just realised that I forgot to add the cheese!!! And we still enjoyed this!
