Around the holidays, search craft stores for Christmas tree-shaped papier-mâché boxes. Use the lid of the box as a serving tray. Place double-sided tape on the circumference of the lid, and cover tape with a length of festive ribbon. Line inside of box with foil or parchment paper. Arrange vegetables as desired.
Use mini star- or heart-shaped cookie cutters to cut shapes from yellow and red bell peppers or thick slices of cheese. Top the tree platter with a star cutout, and trim the vegetable tree with heart-shaped cutouts. Or try using red bell pepper strips as garland.
