The seven flavor axes of the whole sandwich, each summed across its layers. The shaded ring is the catalog's middle 80%; the small number under each axis is where this sandwich falls in the catalog. A shape that sits inside the ring is in the range most sandwiches live in; a spike past it is where this one stands apart.

## What each layer brings

| Layer                                | Role    | Flavor and texture                 | Points    |

Points: what the Sandwich Score would lose if that one layer were left out, everything else the same. A negative number means the sandwich scores higher without it. Flavor runs 0 to 5 on each axis.

## Pairings

- **Chicken + Bacon**: chicken club logic: smoke on a lean bird
- **Chicken + Teriyaki Sauce**: teriyaki is grilled chicken's glaze
- **Onion + Bell Pepper**: peppers and onions, the griddle pair
- **Onion + Teriyaki Sauce**: the sweet onion in the glaze
