A smaller topic: I can’t help but admire a roast chicken. I roasted one a week ago, and it’s so versatile into planning leftovers and meals. The original meal was roast chicken over vegetables and couscous. Then I made beans the next day which opened up tacos. Sliced the breast thin into a sandwich. I had a bag of frozen pita, which I toasted and stuffed with chicken and couscous and lettuce. Any soup works. Omelettes. Using the juices to make a gravy. Which I parlayed into poutine.
Nothing revolutionary or something every family cook realized centuries ago. But something satisfying about looking inside a fridge, and making a new combination on the spot.
