My lazy day meal: Pasta casserole that you can make with ANYTHING

This is my first go-to meal when in a rush, busy, or having a lazy day. I usually use all my leftovers in this casserole bake. I make it with even my frozen vegetables, whatever protein I have starting from bacon, chicken ... whatever. Then I make what we call "stuvning" in Sweden; the creamy sauce that holds the ingredients together and makes a magical taste.  

In this specific casserole, I added my grilled chicken leftovers, frozen broccoli, and green beans, two types of pasta which I had very few left of both. And milk, cheese, butter, stock, and flour as shown in the picture below. 

Here is a basic recipe from the original source, there you can find all the details about this type of pasta bake dish. Enjoy!
