1/2 cup chopped walnuts
1/2 cup ground flax seed
1/2 cup nutritional yeast
3 tbls olive oil
3 cloves garlic
1 tsp salt
3 tsps black pepper
2 tsp crushed pepper flakes
2 tbls hot sauce
1-2 cups pasta water
2 heaping spoonsfuls vegan mayo
2 handfuls parsley, roughly chopped
1/2 box cooked pasta
Add walnuts, flax seed, yeast, garlic, salt, pepper, pepper flakes, hot sauce and oil to a food processor. Pulse til the bigger pieces are small, then continue to process to create a paste.
As an alternative to using a food processor you could grind the walnuts in a coffee/spice grinder. Then form the paste with the ingredients by hand using a wooden spoon. I bought ground flax seed, but you could buy whole and grind that as well. You'd also need to microplane your garlic.
Remove to a large bowl. Add 1/2 cup pasta water and stir to combine. Stir in cooked pasta. Continue adding pasta water until a somewhat loose sauce coats the pasta. Stir in parsley and vegan mayo. Stir until creamy and smooth. Add a little more pasta water if neccessary to get the desired consistancy.
If you have leftovers later on, you can add a little more water and stir to loosen things up a bit. When this chills in the fridge it does tighten quite a bit.
