Choose the board you will use. You can use a quarter sheet pan, half sheet pan, cutting board, or other trays you have at home. Make sure to give it a good wash.
Prep all of the ingredients you'll be using. Cut the meat into slices, cut the cheese into stars (or slices), wash the berries, etc. (See above for different red, white and blue options!!)
When ready to enjoy, put the flag together! Start with a line of red at the top, then alternate white and red until you've reached the bottom (making sure to keep the blue section open).
Fill in the blue section, then top with a star (I use a cheese sliced cut with a star-shaped cookie cutter).
Keep the board cold while serving and enjoy!!!
