It is shown that a combined chiral and 1/N-c expansion of the Bethe-Salpeter interaction kernel leads to a good description of the kaon-nucleon, antikaon-nucleon and pion-nucleon scattering data typically up to laboratory momenta of p(1ab) similar or equal to 500 MeV. We solve the covariant coupled channel Bethe-Salpeter equation with the interaction kernel truncated to chiral order Q(3) where we include only, those terms which are leading in the large N-c limit of QCD.
