Panera Bread Spicy Fiesta Chicken

High histamine

This sandwich is high, driven by the marinated steak, provolone, and garlic aioli.

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.

Gluten Dairy DAO Blocker Histamine Liberator

This is marinated steak with provolone, caramelized onions, garlic aioli, and cherry peppers on ciabatta, and the fillings drive it high.

  • Steak and provolone lead — the marinated steak runs high, and provolone is high from aging.

  • Aioli and peppers add on — the garlic aioli is high and also blocks the DAO enzyme, and the diced sweet cherry peppers sit at moderate.

The ciabatta and caramelized onions are the milder parts, so a lighter build helps, though the steak keeps it up unless you switch proteins.
