Good question!
As black, simply castling is the best response. If the bishop and knight decide to trade themselves for a rook and a pawn, black has the advantage since two minor peices are generally superior to a rook and a pawn, especially in the opening. This becomes evident when you think about how many squares each can cover: a bishop and knight can cover far more than a rook and a pawn. After castling, white's knight is stranded too far forward, and very likely to move back several moves later.
