Fill a Christmas tree shaped tray or pan with broccoli florets. The broccoli should be cut to the depth of the pan. Once the pan is full, prop the broccoli up to make it appear that the "tree" is lush and green.
Insert baby carrots into the broccoli so that just the tips show. These are the ornaments on the tree.
Insert cherry tomatoes for more "ornaments".
Place a small bowl (star-shaped?) at the top of the pan filled with Ranch dressing.
