Last year, I taught myself how to can. I did not do any pressure canning, but will be venturing into that this year. I did tomatoes, along with spaghetti sauce and tomato sauce. I also pickled peppers, green beans and made lots of pickles, that did not last as long as I had hoped! I was able to get fruit from local orchards, so had some apricots, peaches and apples as well. I had a great time, and learned a lot! These are a few of the websites I referred to, and the pickle recipe I used, that everyone LOVED! I hope these are helpful!

There are a lot of others that I have saved on Pinterest, and will be going through them this year, as I need to put up probably 2-3x what I did last year. Here is my Pinterest board: http://pinterest.com/rvdavis/canning-and-food-preservation/
