I really like polenta, either as a mush-type cereal starch with butter, or with sauce, or formed and fried as solotripper suggests.

I got some instant polenta from Packit Gourmet before our last canoe trip and tried it out at home.  It was surprisingly good for an instant food (cooks in one minute) and I intended to take it along on our trip and then forgot!  (Am having a lot of senior moments these days.)

I also made a really good spaghetti sauce on this last trip with foods ordered from Packit Gourmet, the tomato powder (add water and you have tomato paste--it is in a tiny packet and weighs NOTHING!), some f/d tomato pieces, mushroom pieces, onion dices, and some Italian spices I took along in an envelope.  It was very tasty and would be excellent over polenta.  We had it over three-cheese tortellini, but I can see the polenta as another tasty choice.
