What can I do on 2.5 acre (1 hectare) mediterranean climate?

Hi, what can I achieve on 2.5 acre property in that climate?

Is there enough space for self sustaining a family of 4 plus some extra production to sell? What can I expect realistically?

I can’t eat many fruits but I need for my diet quite some legumes, vegetables and some nuts or things like that.

Would there be space for chickens and maybe a couple of animals like sheep or donkey?

Is there any design I can look at to take inspiration within my climate?

Thank you!
