The method for filling red peppers (3) having a cavity, comprises inserting a filling mandrel (2) in the cavity of the red pepper and then filling with cheese over the cavity. A relative movement between the filling mandrel and the red pepper is produced through the pressure of the cheese introduced into the cavity and the filling process is interrupted, when the filling mandrel and the red pepper reach a determined relative position. An independent claim is included for a device for filling red pepper having a cavity with cheese.
