How do I refresh a bagette in the oven?

[HauntedLittleLunatic]

I am sure that Tesco's bagettes have instructions on how to "refresh" them. Something along the lines of pop in oven for a few minutes.

But I don't know the details. I am thinking 5mins wrapped in foil. Sprinkling of water?

Yep - sprinkle with water, wrap in foil and put it in the oven at 250c for 5-10 min, and eat immediately.
