Start with big board, using one with edges is easiest.
Place burgers on first - a small cake stand is perfect to give some height (it also allows you to add more items on the board itself).
Place bowls with condiments.
Then fill with largest items in first like the buns, red onions, tomatoes and watermelon or other items to nibble on.
Then add next largest items like the cheese, bacon and larger pickles.
Add another section of medium size items like lettuce.
Fill holes with smallest items like cherries, pickles and jalapeños slices.
