Bid one spade.

When you are at favorable vulnerability, you should never pass partner's opening bid with a hand unable to defeat the opposition's three notrump game. Favorable vulnerability is an advantage when you hold a weak hand. You can make blocking bids, which make it difficult for the opponents to gauge their combined strength.
