By the time I used a pot and a pan and prepared an oven dish I decided against making a rue cheese sauce and side stepped it to a cheesy tray bake to finish everything.
The instructions are bonkers and I don’t know why butter would not be included or even an explanation to make the sauce.
I like few ingredients, few dishes, easy prep meals and this was not it. Far from one dish.
It is worth noting that everyone loved my tray bake!
