My buddy at work Anne has asked me about these. It really is the easiest damn thing to make and super inexpensive. I have the spices in my house all the time anyway and pay practically nothing for the turkey ($3.49 for 1.2 lbs, all natural from Shady Farms). Other than the fact that you have to touch the raw meat (thats Anne's hold back) it really is delicious and easy. A small dinner role (I buy Mastrianni's. They are surprisingly good for you in comparison to a lot of other breads), a half a slice of Munster cheese, and one sausage patty. It's quick, portable, home made, and really pretty good for you.
It's not as good as Grandpa Jack's, but it's damn good and nice and healthy.
