Cook pasta according to package instructions.
While water boils and pasta cooks, add the Tofu to a food processor and blend until smooth, then add all the rest of the ingredients except the Tapioca Starch.Dijon Mustard Note - I recommend adding 1 tsp of Dijon, and more as you go since not all Dijons have the same level of acidity.Sazon Note - Sazon will give this a more vivid orange / yellow hue. The kind of Nutritional Yeast will also color it differently. Add that mixture to a pot and heat on medium low. Once pasta has been cooked to your liking, add it to the pot with the tofu cheese sauce. Reserve at least 1 cup of pasta water. I like to use a slotted spider spoon to transfer the pasta to the tofu cheese sauce.
Stir to combine, it will be very loose, and a bit watery. This is ok! Add 1 Tbsp of tapioca starch and stir to combine. Heat over medium low, the tapioca starch will thicken the sauce. If you want it thicker, add 1 tsp of Tapioca Starch at a time until it's at your desired thickness.
Now pour in about 1/4 cup of the pasta water. Stir to combine, the sauce should get creamier. Continue adding splashes of pasta water until it's at your desired thickness.
Season to taste adding anything you like and enjoy!
