    "abstract": "We study the N pi N coupling, in the framework of a QCD-inspired confining\nNambu-Jona-Lasinio model. A simple relativistic confining and instantaneous\nquark model is reviewed. The Salpeter equation for the nucleon and the boosted\npion is solved. The f [n pi n] and f[n pi Delta] couplings are calculated and\nthey turn out to be reasonably good. The sensibility of f[n pi n] and f[n pi\nDelta] to confinement, chiral symmetry breaking and Lorentz invariance is\nbriefly discussed.",
