About 50 years ago a co-worker said to have on hand these ingredients and in 5 minutes you can have a meal for 4.
1 onion, 1 pkg smokey links (in freezer), 1 can green beans, 1 can sliced white potatoes, 1 or 2 tablespoons oil. Heat oil in skillet, add chopped up onion and cook until onion soft, add drained green beans and potatoes. Add as much reserved liquid from cans as you like. Dinner for 4.
