We document that N({pi},e{sup +}e{sup -})N measurements will provide new information about the nucleon time-like form factor in the {phi} meson region including the value of the {phi}N coupling constant, g{sub {phi}}{sub NN}. Using vector meson dominance and a field theoretical model which describes pion photoproduction data, we report crossing predictions for the N({pi},e{sup +}e{sup -})N cross section which exhibit dramatic, several order of magnitude enhancements from {phi}N coupling in the nucleon form factors. These narrow, dual peaked resonances provide a novel experimental signature for OZI violation and the related strangeness content of the nucleon.
