1. Toast bagel halves lightly just before assembling so they stay crisp on the board.

2. Spoon cream cheeses into separate ramekins; crumble goat cheese and place near the spreads.

3. Create salmon ribbons by gently folding slices and stacking for height.

4. Arrange cucumber, tomato, and onion in neat rows for easy grab-and-build assembly.

5. Scatter capers and dill near the salmon; add lemon wedges for squeezing.

6. Dust the board and spreads with everything seasoning and set tongs near the bagels.

7. Encourage guests to build their own with a simple sign: bagel + cream cheese + salmon + veg + dill + lemon.
