While we've covered the wonders of this daily quest before, there is a great little trick to cut down on the time necessary to farm the food... and that is to create you own cupboard of food! While your cupboard might seem bare and filled with mostly Ramen Noodles at first, within a couple weeks of quests you'll find yourself well stocked with all the gourmet items you could ever want.
Besides the items you need to have the quest in your log to get, you can store a TON of premade food that'll cut down on your quest time dramatically. The items you want to save up are:
Warp Burgers (from Warped Flesh)
Roasted Clefthoof (from Clefthoof Meat)
(from Serpent Flesh)
Now the key to getting these items, instead of having to go and farm them day after day, is to select the reward of a "Crate of Meat" when turning in the daily quest. The crate will drop the raw form of the above food often enough, and within two weeks time, you'll have more Mok'Nathal short ribs then you know what to do with! In fact, after a month of doing this quest, your cupboard will be so large that you can sell a large portion of it on the AH and make quite a nice bit of gold.
