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.

Pumpkin is one of the only carbohydrates that are allowed in GAPS diet, so take advantage of this!
Pumpkin may be prepared in very different ways: boiled, baked, fried; and it may be used in both savoury and sweet dishes.
Here are some recipes with pumpkin that I suggest:

 

These tarts are made without any kind of flour. An apple is used for the tart base or crust, in which a filling that could be fruit puré or chocolate or whatever one wishes can be filled with;  and on top there is fruit like strawberries, blueberries or raspberries.

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.


 

Gazpacho is a very refreshing entrée dish that is traditionally eaten in the summer in Spain. Gazpacho is usually made of tomato, onion and cucumber, but in the last years watermelon gazpacho has begun to spread in Spanish restaurants. 
You can adapt the ingredients depending on the family preferences: the ratio between tomato and watermelon, avoiding onion if the children doesn’t like it, etc.
Watermelon gives a sweet taste and together with the savoury test of the classical gazpacho creates this sweet and salty delicious taste.
