John357,Do you use any kind of stock or do you let the ingredients do the flavoring?
Personally I wouldn't. I add a small amount of water as necessary, but Leczo is one of those things that is nice because of the clean flavour. There are also usually tomatoes. Some people add zucchini, sugar and garlic though I don't.
Really, all it contains is a lot (in Poland they really do use a lot) of bell peppers, onions, tomatoes, kielbasa, paprika and a little salt.
Sometimes people serve it as an accompaniment to meat, and usually boil it to a mush. In my opinion it is good as a main dish itself, if it isn't boiled down too much.
