Place eggs in a pot. Fill with cold water, 1 inch above the eggs. Bring the water to a rapid boil on the stovetop over high heat. Once the water comes to a boil, cover the pan with a lid and remove from the heat. Set a timer for 10 minutes.
Halve and toast the bagels to preference.
While your eggs are hard-boiling, begin to fill in your board. Start with the ramekins of cream cheese, butter, marmalade, and capers. Add toasted bagels to the board. These will be the focal point of your board, so place them in opposite corners.
Add your larger fruits like grapes, oranges, and grapefruit slices.
When your eggs are finished, carefully remove them from the water. Peel and cut the eggs in half.
Place a small piece of parchment or baking paper on your board and layer in the lox. In remaining space on the board add your veggies, eggs, cheese, nuts, and garnish.
