We extend the gauge invariant variational approach of Phys. Rev. D52 (1995)3719, hep-th/9408081, to theories with fermions. As the simplest example weconsider the massless Schwinger model in 1+1 dimensions. We show that in thissolvable model the simple variational calculation gives exact results.Comment: 14 pages, 1 figur
