DAR food
"DAR food" refers to bland or badly made meals, often using canned or overcooked vegetables, or frozen or instant prepared foods, or just prepared without any seasoning or skill or imagination. It includes home-made casseroles made by combining things like canned soups with canned vegetables and cheese from an aerosol can. It's a derogatory word used to refer to American food that is not from any foreign ethnic tradition.
Our club had a pot luck dinner. People brought their delicious Chinese and Indian and Italian and Hungarian and Portuguese specialties. But then Janey brought DAR food: one of those awful green bean casseroles made of nothing but canned ingredients.
