Grilled Poor Man’s Lobster Kebabs

If you are pressed for time, purchase the Italian polenta ready in a sealed plastic bag; it works better for this preparation than the instant polenta. If you cook the polenta in a shallow sauteuse pan, you will gain time; when you test the polenta for thickness, tilt the pan and bunch the polenta into its lip. If a spoon stands in the polenta, it is ready.
