We suggest that generalized parton distributions can be probed in charged current meson production process, $ep\to \nu_e\pi^{-}p$. In contrast to pion photoproduction, this process is sensitive to the unpolarized GPDs $H,E$, and for this reason has a very small contamination by higher twist and Bethe-Heitler type contributions. Since all produced hadrons are charged, we expect that the kinematics of this process could be easily reconstructed. We estimated the cross-sections in the kinematics of upgraded 12 GeV Jefferson Laboratory experiments and found that thanks to large luminosity the process can be measured with reasonable statistics. The talk is partially based on our recent publication [Phys. Rev. D 96, 096006][1]. [1]:
