Another experiment for lunch. The same Salisbury steak preparation but the french fries were an attempt to resuscitate doggy-bag fries. These I had frozen a few days ago after bringing them home from a restaurant. I reheated them on a rack in the Breville Smart Oven at 425°F convection roast for six minutes and they were quite edible.
Edited to add that the Salisbury steak was reheated in the Cuisinart Steam Oven at 325°F on the steam-bake function for 15 minutes.
