There’s no specific way to assemble these boards but some general guidelines:
Assemble your small dishes/bowls on the board. The food will be placed around these; try to make it asymmetrical.
Pre-cut all of your fruits and veggies before. You can get creative when it comes to slicing and dicing these too!
Have a little bit of each food in different places; you want it to look very colorful.
For your finishing touches, you can add some décor to the board such as fresh herbs, flowers, cheese knives or a honey dipper.
