I think you need cows to get milk from.
Yes, and an egg tree, clearly.
No, seriously, obviously you'd need hens and sheep, cows or goats. People here lived like that for about 2000 years, with some added pigs if they could afford them. My father's family are Sami though, and that's a very different lifestyle. Semi-nomadic hunters/gatherers who slowly drifted into "keeping" herds of reindeer. They still live pretty traditionally and keep reindeer:

If I could persuade some of those relatives to take me in, I'd probably be good to go.
