It is pretty boring on its own! Some people suggest deep frying it, but personally I find that it absorbs too much oil and is more of a snack than a meal in any case.
We like it best mixed or topped with cheese, parmesan is less greasy, left to set in a tin, grilled and then cut up. You can add other toppings if you like.
If you Google "grilled polenta toppings" there are loads of recipes and pictures. You can see from the google images that it looks much more appetizing if it is grilled, and the cheese (or herbs and spices) makes it actually taste of something.
My mother was coeliac and loved orange or lemon polenta cake which is, I guess, what previous posters have called lemon drizzle cake.
