Place potatoes, carrots, water (should be enough to come about 1/2 inch from the top of the potatoes and carrots), salt, chicken seasoning, onion powder and garlic salt together in a pot, mix together, and cook on medium heat till potatoes and carrots are soft.
While veggies are cooking, heat water for ziti noodles; when boiling add ziti noodles.
Cook till al dente.
When veggies are done, cool or add a couple ice cubes to cool it down.
Blend together with nutritional yeast flakes and oil until smooth.
Add more water if it's too thick, add more salt if needed, should be a little on the salty side as the pasta will absorb some of the salt.
Drain the ziti noodles.
Pour"cheese" sauce over ziti noodles in a casserole dish and mix inches.
