Is that common with the stated definition? In the US, it is not especially if you add sustaining levels of production vs just hobby level
For example, the Great British Bake-off has the tent in the garden. But no red blooded 'murican would consider that expanse of manicured grass as a garden.
This year we may do squashes and eggplants ...
That's true - there's nothing in the world that tastes like fresh-cut cilantro (definitely not day old cilantro). Unfortunately, it takes a lot of work to keep a cilantro plant from bolting.
In addition to the items you've listed, I'd add grapes/ muscadines, passionfruit (grows wild so cheating), fruit and nut trees (figs are easy if you keep them pruned), berries, tea, lettuce/greens, celery, potatoes, carrots, herbs. I used to hate gardening, but it's grown on me over the last few years. The only thing I don't like growing is squash really.
Gardening really is a hobby more than a practical life-hack. Although we did just get a hydroponic setup for greens in the house, and hopefully that can supply greens that are better and actually much cheaper.
