I made Corned Beef Hash 2 nights ago.
Caramelize three onions in fry pan, and throw in one can of diced up Spam (Didn't have any corned beef). After onions and Spam brown for a bit, you can never tell it was not corned beef. Throw in 6 diced up potatoes. Fry until desired brownness.
Kids loved it!
Wifey even said "This is good! What kind of meet is it?"
