A new formulation of the quasilinear theory of weakly turbulent plasmas is presented, which explicitly separates resonant and nonresonant wave-particle interactions from the outset. This is achieved by milking a canonical- transformation to oscillation center variables'' before attempting to solve the Vlasoy equation. A systematic method of constructing the generating function to any order in twc wavw amplitude is presented, based on a variant of Hamilton- Jacobi perturbation theory. Momentum and energy split naturally into a wave and a particle component. The results are generalized to apply to weakly inhomogeneous plasmas, and verified by demonstrating momentum and energy conservation. (auth)
