Some of the best foods out there are ones that also happen to have a touch of nostalgia to them, so i am always up for trying out a retro casserole when it comes my way. And luckily with our recipe tin project there are plenty of interesting vintage casseroles. This french chicken broccoli casserole is just one of them, a cheesy and easy bake that came from a well-loved index card with lovely red script and a few smudges and splotches.
