There are a lot of vegan mac and cheese recipes all over the internet. What makes this one a little different is the use of silken tofu. I think it creates the ideal cheese sauce texture and viscosity.

Since tofu has no fat and real cheese has fat I used some olive oil to add the richness you'd expect.

White mushrooms add the umami factor to bring it all together. Some chick peas and their aquafaba complete the creaminess profile.

Cheese Sauce
1 12 ounce container silken firm tofu, drained
2/3 cup nutritional yeast flakes
1/2 pint button mushrooms
1 tbl spicy mustard
1/3 cup chick peas + 2 tbls aquafaba
1/3 cup almond milk
3 cloves garlic
3 tbls olive oil
2 tsps turmeric
2 tsps paprika
3 tsps garlic powder
1 tsp onion powder
1 tsp cayenne powder
1 tsp crushed pepper flakes
3 tsps salt
2 tsps black pepper

This makes enough sauce for an entire box of elbow macaroni.

It's surprisingly easy to make. The list of ingredients migth seem kinda long, but most of them, if not all,  you probably already have on hand. Buzz up all the components in a food processor until smooth and creamy.

Pour sauce over cooked and drained macaroni. Retain a few tablespoons of the pasta water in the mix to starch things up a bit.

At this point you can simply serve it in a bowl and add your garnishes.
