We report on a non-perturbative study of D=2 N=(2,2) super QCD. Our lattice formulation retains an exact supersymmetry at non-zero lattice spacing. In addition to the gauge bosons and fermions found in a U(N_c) super Yang-Mills theory this model also contains N_f fermions and scalars transforming in the fundamental representation of the gauge group. We present evidence that the exact supersymmetry breaks spontaneously when N_f is less than N_c in agreement with theoretical expectations.
