We consider baryons in a two-flavor Nambu-Jona-Lasinio-type model for self-interacting quarks in the large-N limit using mean-field-theory techniques. We show that for slowly varying mean fields, all baryon properties are exactly those obtained from collective-coordinate quantization of the soliton in a nonlinear σ model of mesons. We also indicate how the higher Fermi couplings can stabilize the soliton.
