Eyescream ( very easy to make) + Wolf skever + onion soup are good enogh for plains.
Just be sure you have some good armor on you and always carry a shield (or weapon to parry the moskitos).
I also recomend a anti-poision potion if you go near the new monsters as they hurt a lot.

Also, use stamina food 3x when doing some basic non-danger stuff (like getting wood or stone) and save the good stuff for harder parts. If you are at that point of game with strong armor, the basic mobs will do almost no damage to you.
