We extend the gauge invariant variational approach of I. Kogan and A. Kovner [Phys. Rev. D 51, 1948 (1995)] to theories with fermions. As the simplest example we consider the massless Schwinger model in 1+1 dimensions. We show that in this solvable model the simple variational calculation gives exact results.
