In this talk I describe work on computing non-leptonic matrix elementsconsistently with both long and short distance contributions included. On thesimpler example of the $\pi^+$-$\pi^0$ mass difference I explain in detail thematching procedure and the difference between various low-energy models. I thenexplain the new difficulties in non-leptonic Kaon decays and how the matchinghere can in principle be done in the same way when scheme dependences arecorrectly accounted for. In the end I summarize the results J. Prades and Iobtain for the $\Delta I=1/2$ rule and $B_6$.Comment: 10 pages, uses aipproc.cls, to appear in the proceedings of the  International Workshop on Hadron Physics `Effective Theories of Low Energy  QCD', Coimbra, Portugal, September 10-15, 199
