the best thing to say since you don't have much participation is "I wasn't very involved last year and that is one of the many reasons I am going through recruitment, I think joining a sorority is an excellent way to get more involved on campus and with philanthropies, I know that (insert sorority) is very active in (insert organization, community service, philanthropy) can you tell me more about it?"

You can also express interest in taking leadership roles in the sorority (that is, if you are interested). IMO, all else equal, I'd prefer a PNM who has less experience and more enthusiasm about committing to and participating actively in the sorority than a PNM with an impressive "resume" only to be "just" a sister.
