As others have mentioned, space is going to be your biggest issue. You’ll need a fair amount to get anywhere near self sufficiency even in summer. I put in a a few raised beds a couple of years ago and it's just enough for a start. Last year I added a 10x12' raised bed which now has a few raspberry canes a a row of Strawberries, so i'm looking forward to some home grown fruit again. I'll be adding more strawberries this year as IMO you need at least 20 plants to make them worthwhile. I'm thinking of adding another 10x8' bed for veg as well. 30m2 should be enough hopefully!
I used to grow a lot of stuff when I was younger, but started again a couple of summers ago when I moved over here. It’s a different challenge - no slugs (too dry), but a growing season of <100 days (last frost at the end of May, first beginning/mid Sept), ground frozen solid until mid April, large tomato (and car) destroying hail storms in July/August and snow, well, any time..
Lettuce/salad leaves, Russian kale, carrots/Beetroot and peas are easy to grow and don’t take much space (carrots will need good soft ground though) and can work well tiered and layered together as they use different parts of the soil/bed. I prefer salad leaves rather than whole lettuce (Cos, romaine, etc are good) as you can just pick leaves off the plants rather than pull them. I plant one 4 ft row at the beginning of the season, then one a couple of months after, giving enough leaves for the whole summer for two people. Pull them when they start to bolt.
The other main thing I have been planting is tomatoes. I usually put in around 12 plants, although the growing season makes it interesting. I ended up with about 10kg of unripened tomatoes and hardly any ripe ones last year due to an early snowfall.
With the additional space I've got Courgette, Pumpkin and lots more Carrots/Beetroot I'm hoping to grow this year. Also hoping the Apple I planted a couple of years ago, and the Cherry that went in last year, along with Blueberries, Honeyberries and Saskatoons give me a bit more fruit this year - they're all still small/getting established so not much yet. I have a self pollinating kiwi as well, which I'm hoping will develop into something nice.
