the most common way to use polenta could be broken into 2 categories:
-wet polenta : the finish product will have the texture of mash potatoes
-not so wet polenta: when you prepare the polenta use less water , then cool it down, when cold cut it unto slabs and pan fry it or grill it .
a nice way to prepare the not so wet polenta for grilling or panfrying is to add cooked vegetable to the polenta before cooling down ( peppers, red onions, herbs...) then cool down in a tray, pan fry and serve with a salad, shaved parmesan cheese... whatever you want.
