Welcome NewgranGill. Your post about the allotment made me smile ruefully as I'm still undecided whether to grow potatoes again this year. Most of them went to waste last season (or I gave them away) with the exception of a few lovely new ones (I couldn't resist but I smothered them in butter!!)
I confess to eating a few below ground veggies. Carrots, parsnips (poor crop this year so just the odd one) and my downfall....beetroot (with goats cheese
)
But we've grown lots of leeks, lettuce (the pigeons feasted on those), asparagus, cabbage (the caterpillars got those) kale (ditto) green beans, courgettes, sweet corn and radish, and lots of berries -strawberries, raspberries, blackberries, blueberries....perhaps your DH could grow more of these.
