Last autumn, I dropped by my niece’s small cottage near the lake, where she was recovering from teaching her first full year. The leaves were falling fast, and a gentle breeze carried the scent of pine and woodsmoke through the windows. She pulled leftover chicken and rice from the fridge that evening and asked if I could turn them into something cozy and warm.
We browsed the pantry together and landed on a casserole idea, something like Chinese takeout but without the fuss. With a bottle of teriyaki sauce, fresh veggies from her market box, and a sprinkle of cheese, we mixed everything in a baking dish. I remember watching her stir in bright peas and broccoli, her face lighting up with that “home kitchen” satisfaction.
By the time it came out of the oven, the golden cheese was bubbling, and the sauce caramelized slightly around the edges. We scooped out bowls and sat at her tiny table, the wood still warm from dinner dishes, savoring each bite. One more turn, one more crackle of cheese, a breath of steam and the moment felt like a warm embrace.
