What is a Grillade, I guess a BBQ, but we are not sure whether we need to bring anything? It is for Pfadi - It says to bring cutlary, but not sure about a sausage?

Grillade is indeed a BBQ - but not whether it is provided by host or bring your own. You need to ask the organisers who should have made it clear from the start. Enjoy.

In our area (Zurich) it is typically BYO unless stated otherwise so maybe pack a few sausages in a cooling bag if you cant clarify in advance...

it is grilled meat, another word for a steak, grilled piece of meat. and in doubt id bring a sausage along to the pfadi/any bbq.

Yep the kids needed to take something, but they didn't so the other Cubs shared their food a bit... It told us to take knives, a fork and a plate. Will know next time!

A pity you didn't check with the organisers first
