We propose a method for determining γ using B ±→DK± decays followed by a multibody D decay, such as D→KSπ-π+, D→KSK-K+, and D→KSπ -π+π0. The main advantages of the method are that it uses only Cabibbo allowed D decays, and that large strong phases are expected due to the presence of resonances. Since no knowledge about the resonance structure is needed, γ can be extracted without any hadronic uncertainty.
