A toy model of strongly correlated fermions is studied using Green function and functional integration methods. The model exhibits a metal-insulator transition as the interaction is varied. In the case of unrestricted hopping an equivalence of the model with the Hubbard model with infinite range hopping is established. The generalization to the case with N components is made.
