Do you use Velveeta?
Perhaps the Cheese/Salsa Dip??
And, I do have a great recipe for Homemade Mac & Cheese
that uses a Processed Cheese Product.
Anyway, it is packaged in the most sturdy little boxes...
they are the perfect size to slide into your junk drawer.
This is the "junk drawer"
in our FACS demonstration kitchen.
If you wanted to 'go crazy'
you could even line the boxes with contact paper...
