Here is a hack. Menu has a constructor Menu(String text, Node graphic). Set the String to empty-string and the Node to Label. Then add a MouseListener to the Label.

import javafx.application.Application;
import javafx.scene.Scene;
import javafx.scene.control.Label;
import javafx.scene.control.Menu;
import javafx.scene.control.MenuBar;
import javafx.scene.layout.StackPane;
import javafx.stage.Stage;

/**
 *
 * @author Sedrick
 */
public class JavaFXApplication33 extends Application {

    @Override
    public void start(Stage primaryStage) {
        Label label = new Label("Help!");
        label.setOnMouseClicked(mouseEvent->{System.out.println("Hello World!");});
        Menu menu = new Menu("", label);
        MenuBar menuBar = new MenuBar();
        menuBar.getMenus().add(menu);


        StackPane root = new StackPane();
        root.getChildren().add(menuBar);

        Scene scene = new Scene(root, 300, 250);

        primaryStage.setTitle("Hello World!");
        primaryStage.setScene(scene);
        primaryStage.show();
    }

    /**
     * @param args the command line arguments
     */
    public static void main(String[] args) {
        launch(args);
    }

}
