Blackcurrants or tayberries or blueberries.
I have two blackcurrant bushes and get lots of berries. I only have one tayberry and its also covered in fruits, it sends up new stalks every year and I cut down the old ones. Blueberries I have three and they are planted in ericaceous, again lots of berries.
I would suggest rhubarb, but that is best on its own.
