Firehouse Subs Cherry Pepper Rings

High histamine

These cherry pepper rings are high in histamine because the peppers sit in vinegar.

Food here is usually assembled to order from components that were prepped earlier in the day, so it tends to be fresher than a drive-through and less fresh than cooking at home. Histamine builds up as protein foods sit, so how long the chicken or beef has been in the warmer matters as much as what is in the bowl. Treat the rating above as a starting point.

This is a simple topping of sliced cherry peppers packed in vinegar and salt.

  • Cherry peppers in vinegar — the peppers themselves run high, and the vinegar brine they sit in adds a moderate layer on top, so the whole jar lands high.

  • It's a condiment, not the meal — because this is just a pepper topping, leaving it off is the easiest way to keep your sub lower without changing much else.

On a sub, the peppers are optional, so this is an easy one to skip.
