What do you normally buy? If you live on potatoes then your food bill is very low and you should grow potatoes to bring it down.
But potatoes are also very cheap to buy, which makes them a poor choice if you want high value per m². Herbs are what I started with in my garden. Rosemary, sage, chives and mint. Got some bay trees that I started from cuttings last year, hopefully they will become productive at some point.
Then got an allotment this year, high value crops I have are:
Jerusalem artichokes - tubers that are used like potatoes but rarely see them in shops and when you do they cost a lot. Related to sunflowers.
Taunton Deane kale - a perennial kale that grows up to 2m tall.

Hope to keep growing both for years to come.
