I’m planting vegetables and vine fruits. I find it very relaxing. My grandkids love it too. Start small and add as you like. I don’t know how to can (yet) so I plan to do a lot of freezing.
You can actually achieve a better product by freezing corn, green beans, and most other veggies. Same for soups and stews.
I'm a big "canner"...but I don't bother with things that need the pressure cooker. You can safely can: jellies and jams; pickles; salsa; tomato juice; diced tomatoes (even those that are flavored with spices)...anything that is higher in acid using a boiling water canning method.
The USDA has a terrific site with recipes and instructions.
They now recommend that spaghetti sauce be pressure-canned; so I freeze it. Here's the website (BTW, I think it also gives instruction for freezing homegrown or fresh-purchased produce):

In mid-February, I helped my son to relocate from San Dieog to Pocatello. The extra costs of assisting him have necessitated a change in our dining habits. He was over this afternoon and spent about 5 hours making a very high quality Vietnamese phở bò (rice noodle soup with rare steak). He also cooked some outstanding carne asada a couple weeks ago. I'm going to have to jump into the fray with some Thai green curry with chicken. For the less timid, I make the chicken curry with habaneros. We have lots of fun creating good food in the kitchen. Most of it is exotic stuff we can't order at any restaurant.
