We report measurements of K$^{*}$(892)$^{0}$ resonance and \ph(1020) meson production in \pPb~collisions at \sqrtSnnE{5.02}.
\ks~and \ph~are reconstructed via their decay into charged hadrons with the ALICE detector in the rapidity range -0.5 \textless~\y~\textless~0. The  transverse momentum spectra, measured as a function of the multiplicity, range from 0 to 15 \GeVc~for \ks~and from 0.3 to 21 \GeVc~for \ph. Integrated yields, mean transverse momenta and particle ratios are reported in comparison with results in pp and \PbPb~collisions. In \PbPb~and \pPb~collisions \ks~and \ph~probe the hadronic phase of the system and contribute to the study of particle formation mechanisms by comparison with other identified hadrons. For this purpose, the mean transverse momenta and the differential proton-to-\ph~ratio are discussed as a function of the centrality of the event. The short-lived \ks~is measured to investigate re-scattering effects, ultimately related to the size of the system and to the lifetime of the hadronic phase.
