What to serve with it

Assemble just before eating to protect the toasted edges. Serve any cool vegetables on top at the last moment; avoid stacking hot portions where trapped steam softens them.

Storage & reheating

Refrigerate in a shallow covered container within 2 hours and use within 3 days. Reheat cooked leftovers to 165°F throughout; keep any raw salad garnish separate.
