Savoury breakfast for a crowd that can sit out

Note soft cheeses are PHF's due to moisture content. How about an herbed focaccia?

Thanks, ChefOno. It will be more than 4 hours so quiche is out. To be on the safe side I think cheeses and accompaniments might be he way to go.

You're absolutely correct to be concerned about food safety here Amandadp. Without a better definition of "quite a few hours without refrigeration" you're flirting with serious danger. Normally I won't cite commercial rules outside a professional environment because, without a complete understanding of the complexities, they can be taken out of context and do more harm than good. This might be an appropriate exception so here goes: In general, the maximum time a Potentially Hazardous Food may sit out is 4 hours, after which it must be discarded. And just to be clear, quiche is a PHF. Also: Forget taking home any leftovers.

Thanks for the ideas! I was thinking quiche but wasn't sure about leaving it out unrefrigerated.

As mentioned, quiche is great. Believe it or not, the South Beach diet has "quiche cups to go". Those are individual mini-muffin quiches with veggies & cheese. Tasty & easy to transport.

A quiche (or quiches) would be perfect. You don't have to add pork meat, you could leave them vegetarian and the eggs and cheese would still be filling enough. They also are delicious warm, room temp, or cold, so leaving them out for a little while would be fine.

Quiche or frittatas.

Bagels, lox and all the fixings (cream cheese, red onions, capers)!
