Red Onion Tree- Cut a small slice of shallot for the tree scar and then cut slices of red onion and slice a radius into slices to create long strips of onions for the branches and trunk of the tree. Soften onions so that they lay flat, by heating them in a warm oven for 3-5 minutes. Remove from oven and let cool enough to handle. Assemble a mock up scene on a cutting board.
Carrot Pumpkins- Peel the large end of a carrot and cut off a 3 inch section of the large end. Use a knife to cut two vertical shallow cuts on the 3 inch section of carrot to form the stem and then cut perpendicular to the vertical stem cut to wedge out of the carrot on each side of the stem. Slice carrot into thin slices to create pumpkin slices.
Turnip Moon and ghosts- Cut a thin slice from the middle of a turnip to make the full moon. Cut very thin slices to make ghosts using a ghost cookie cutter. The thinner slices of turnips will create a translucent looking ghosts. :)
Pepper Stars- Use a mini star cookie cutter to cut stars out of yellow peppers.
Transfer your mock up from the cutting board to the surface of the focaccia and then garnish with fresh herbs. Sprinkle top of focaccia bread with kosher salt before baking.
Using a bat paper punch or cookie cutter, punch out or cut out a bat from nori seaweed and place in the center of the moon.
In a preheated 425 degree oven, bake for 25-30 minutes. Let cool and serve.
