In order to make healthy food more attractive and special for Christmas meals, there are several options of decorating into different pretty wreaths using different kinds of fruits and vegetables.
I suggest to you one sweet option and two savoury Christmas Wreath options.

In the winter, warm food is more appetising. It is harder to bring oneself to eat fruit, which tends to be cold, and less appetising at this time of year. Although the ideal situation is to eat fruit in its natural form (baked fruit loses some nutrients), it is possible to bake different fruits in the oven to continue benefitting from fruits while staying warm on a cold winter day.
