A very delicious, yet simple comfort food that everyone enjoys. Many, many ago, we were invited for dinner. As the hostess served this from the crock pot, I kicked my "meat and potatoes" DH under the table, knowing he was wondering "What is that???" He licked his plate clean, commented how good it was, and went back for seconds...and thirds. The 4 of us ate the entire 6 servings! On cold winter evenings, DH still requests this often. POTLUCK SUGGESTION: When "hash" is done and still very hot, spread in 9x13-inch casserole dish, top with spring onions and cheese; cover with foil or lid. Cheese will be melted by the time you arrive. You'll return with an empty dish!
