Im not sure how it is on other realms, but on eternal there are no recipes or mats for 250-350 so ill just list what i did to help other people with their cooking.
Once you hit 250, go to felwood and pick up the recipe Charred Bear Kabobs. Check the link for location.

Alliance can get a recipe that uses the same materials from http://www.wowhead.com/npc=2803
There are bears all around felwood that drop the meat for this recipe, just kill them until you get enough to get to 300.
From here you go to outland and pick up this recipe.

Kill these http://www.wowhead.com/npc=16933 until you have enough meat to get to 340 with this recipe.
Then pick up this recipe http://www.wowhead.com/item=27692 and kill the warp stalkers in this zone. They are all over the place. http://www.wowhead.com/npc=18464
After that you are at 350 and you can continue from the cooking trainer at the nearest mall.
Hope it helps.
