Garden carrots are so much better than store bought. Same for tomatoes.

We make pickles and salsa that usually lasts thru most of the winter. We pickled a few green beans also. Haven't got a lot of space so we're nowhere near self-sufficient, but I figure we're gaining knowledge in case self-sufficiency becomes necessary.

Grew a few dozen onions which we took straight from the ground to the kitchen when we needed one.

Also grew about 50 pounds of potatoes this last season. The potatoes seem to last a lot better than store bought, I think this is because the ones from the store have already been in storage for a while when they are sent to the store.
