Recipe - Lasagna Rolls

I have started to look at some old recipes now that the weather is getting colder. I don't like the fact that the weather person said don't expect 60's any time soon. I am just not ready for that. But ready or not the cold is coming so I am looking for some comforting recipes. Here is one I really enjoy.

One question I have for you guys, which is better - organic frozen spinach from China or non-organic local frozen spinach? I know the organic is better but what about all of the pollution put into the air getting it here? Is local always better even if it isn't organic compared to organic from half way across the world?
