Form little patties of polenta or buy that tube stuff. There is some nice organic one available and even some flavoured one (I bought plain to add my own seasonings...)

For a vinaigrette, I pureed with a hand blender some parsley, basil and oregano, garlic, sundried tomatoes, a bit of parmesan, pepper and olive oil.

I put the patties on the bbq, brushed them with the vinaigrette. Also put on the grill some roma tomatoes and portabello mushroom. Brushed those with the vinaigrette. Once one side of the polenta seems crispy, turn it over. Brush some more. Take out the mushroom and tomatoes, slice and put on top of the polenta patties. I then added some provolone and goat cheese. Yum.

We ate those with a nice chilled almond and cucumber soup.
