You're not stuck! You just need heirloom seeds, and tons of compost and you can raise great tasting vegetables. Personally, I get my seeds from http://www.harrisseeds.com (no affiliation) but if you google, you can find many heirloom seed providers - just make sure to talk to them before you buy to make sure they will grow ok in your climate zone - heirlooms are less tolerant of climate ranges than the modern breeds.

As to the strawberries - you're not stuck there either! While personally I can't imagine anyone not preferring gigantor strawberries, to each his own. There is a different breed of species in Europe, you can get them here, they will grow here. I don't remember the exact species/breed, but an heirloom seed supplier will know. You can see the different species on wikipedia: http://en.wikipedia.org/wiki/Fragaria
