2). Go buy the Warp Burger recipe from Innkeeper Grilka in Stonebreaker Hold (Terokkar Forest) and then kill Warp Stalkers/Hunters around Terokkar Forest for about 35-40 meat.
350 to 375
This part really is a problem at the moment. The best way to get to 375 at the moment is by fishing up Furious Crawdads in one of three lakes around Terokkar Forest and then cooking them. However, these lakes are only accessible if you have a flying mount.
The three lakes are:
Lake Jorune - north west of Stonebreaker Hold.
Lake Ere'Noru - south east of Allerian Stronghold.
Blackwind Lake - in the south east corner of the map, in the Skettis area.
You can buy the recipe cheap wow gold from Rungor in Stonebreaker Hold.
You also need a 430+ fishing skill to be able to fish there.
However, you can go to Blade's Edge Mountains and find an NPC called Matron Varah (she's in the Inn in Mok'nathal Village) who gives you a quest to get her Raptor Ribs and Serpent Flesh. Once you complete it, she'll give you the recipe for Crunchy Serpent, which will stay green until 375. You can now kill Scalewing's around Blade's Edge Mountains for Serpent Flesh. You will need about 60 to get to 375.

*Blizzard added recipes for Hot Buttered Trout and Fisherman's Feast. Both of which stay orange till 375. Unfortunately the main component is so far harder to fish up than Crawdads. Hopefully this will change. But if you get any Enormous Barbed Gill Trout or Huge Spotted Fetail then cook them. The recipes are taught by the barmaid in the World's End Tavern in Shattrath City.
