While SPAM is tasty, it is far from economical in plain nutritional terms. At $2.40/12 oz., that works out to about $2.90/lb. Plain ground pork can be had for around $2.00/lb. in this neck of the woods and I’m about an hour’s drive from Austin, MN where SPAM is made.
For my money, I look for pork butt that is currently selling with frequency at, or around, $1.00/lb. When pork goes back up, pork trimmings can be had for under $1.50/lb. It is a very simply task to convert the pork into the most delicious, nutritious and lean sausage you’ve ever eaten. As a matter of fact, I just finished smoking about 15# of Kielbasa last night (well, actually 50/50 venison and pork). Trust me, this is sausage to kill for.
I like SPAM, but I can do much better - and for much less.
I've eaten this hybrid sausage. Venison is always dry and lacking fat so you make a sausage that is 50% pork otherwise it is inedible except to space aliens
