Misty Thicket Picnics are some of the best stat food in the game until I think Planes of Power. In addition to being good stat food, these picnics are also used in the Earring of the Solstice Luclin Quest which increases their value even further once Luclin hits.
Misty Thicket Picnic 226 - 300
As with the Halas 10lb Meat Pies, you will want to sell all of your Misty Thicket Picnics that you're not using. Misty Thicket Pinics are almost always in high demand since they are the best stat food for almost everyone for quite awhile. Each stack of Misty Thicket Picnics can sell for up to 120pp.
