The substitute that works well for me is Cauli and Cheese! Yep, good old cauliflower to the rescue and the best part - it is easy and quicker to make then Mac & Cheese.
The bases is of course, cauliflower and then I add what I want or what I have on hand. Easiest way would be to buy a cut up bag of cauliflower or buy a head and cut of as many florets as are needed.
Ingredients:
Cauliflower
Water
Additions:
Cheese (I prefer a few slices of cheddar)
Butter (I prefer Kerry Gold)
Cream
Green Chiles
Pepper
Etc
First place cut up cauliflower in microwavable bowl and microwave till tender. Then sliver off a few slices of cheese and then add what you like and microwave until melted and warm.
