Expression.Invoke in Entity Framework?

The Entity Framework does not support the Expression.Invoke operator. You receive the following exception when trying to use it:

"The LINQ expression node type 'Invoke' is not supported in LINQ to Entities.

Has anyone got a workaround for this missing functionality? I would like to use the PredicateBuilder detailed here in an Entity Framework context.

Edit 1 @marxidad - I like your suggestion, however it does baffle me somewhat. Can you give some further advice on your proposed solution?

Edit 2 @marxidad - Thanks for the clarification.
