While poking around in DefCooking, I saw this..
So I did it for fun. Both baked & unbaked Chicken & Lamb pies. 
Code:
// TODO: This must also support chicken and lamb legs <<
index = this.AddCraft(typeof(UnbakedMeatPie), 1044496, 1041338, 0.0, 100.0, typeof(Dough), 1044469, 1, 1044253);
this.AddRes(index, typeof(RawRibs), 1044482, 1, 1044253);
