The most important higher-twist subprocess contributing to inclusive single-meson production at high p/sub T/ is photon+quark..-->..meson+quark. We consider two-photon collisions and compare this higher-twist contribution to that arising from the leading-twist subprocess, photon+photon p ..-->..quark+antiquark. We find that the higher-twist subprocess, while not important for direct ..pi.. production, is significant for rho production, especially when enhanced by suitable trigger requirements.
