Begin by preparing the macaroni according to package directions. Do not add any salt. When the macaroni is tender rinse it in cool water and drain well. Next chop and measure the vegetables. Meanwhile, in a large bowl combine all of the other ingredients. This is the dressing. Mix it well. Add the prepared macaroni and vegetables. Mix well and chill for 2 hours, or until serving time. This is a good make-ahead dish for pot-lucks and picnics. Its especially tasty in the summertime.
