I will show that scalar, Light (MeV) Dark Matter has the potential to be explored in high energy hadronic colliders. A coupling between scalar Dark Matter, quarks and a fermionic new particle (F) has not been explored yet. Due to small scalar masses, production of colored and flavored di-F particles in hadron colliders could be surprisingly copious for large coupling constants. Cross sections overcome the nb in some parameter space regions, and are above the pb in most of it. A quick look to the kinematical shape of di-F production shows that it could be distinguished from the background expected from p-p collisions. Therefore, a full experimental analysis is worth.
