In this blackboard presentation, we will outline a new Palatini formalism for Galileon scalar field theories. After a pedagogical review of the Palatini formalism for GR, we will outline how this carries over to the spin-0 case. This will uniquely single out the Galileon symmetry and provides a first-order formalism for such theories. Finally, we present possible extensions including the coupling to gravity.
