If you have not already, cook the pasta — making sure it is cooked
al dente.
*For the squash, peel the squash and then using a food processor shred the squash using the course grater attachment. Alternatively, you can use the large holes on a box grater.
Next, heat a large non-stick fry pan over medium heat. Once hot, add the butter, followed by the onions. Cook for a minute or so, and then add the grated squash.
Let cook for 5 minutes or so, or until the squash and onions have fully cooked through.
At this point, add the pasta to a large bowl and pour in the cheeze sauce. Add the onion and squash and gently stir to evenly distribute the ingredients. Taste for seasoning.
Note: Depending on how creamy you like your macaroni and cheeze, you may wan to add a touch more non-dairy milk (or save some of the pasta water), to thin the sauce out a bit. The recipe as it stands now, is meant to be a somewhat of a drier macaroni and cheeze.
