Using a sample of 25.9 x 10(6) psi(2S) decays acquired with the CLEO-c detector at the CESR e(+)e(-) collider, we report branching fractions for the decays chi(cJ) -> p (p) over bar pi(0), p (p) over bar eta, and p (p) over bar omega, with J = 0, 1, 2. Our results for B(chi(cJ) -> p (p) over bar pi(0)) and B(chi(cJ) -> p (p) over bar eta) are consistent with, but more precise than, previous measurements. Furthermore, we include the first measurement of B(chi(cJ) -> p (p) over bar omega).
