TUESDAY RODDLE

I can sizzle like bacon,

I am made with an egg,

I have plenty of backbone, but lack a good leg,

I peel layers like onions, but still remain whole,

I can be long, like a flagpole, yet fit in a hole.

…what am I?

and also congrats to rob for getting the first one :)
BUT NOT REALLY CUZ HE CHEATED
