Another Macaroni and Cheese

I just tried this macaroni and cheese recipe recently, as it was highly recommended. I didn't have pimentos, so I used tomato paste. It was pretty good but not spectacular. However, my mom just tried the same recipe. She did use pimentos and they said it was amazingly awesome. So, unlike me, if you actually follow the recipe this should turn out very good.

Add the following to 3 quarts boiling water:

3 cups dry macaroni

2 tsp. salt

Cook until done. Meanwhile, blend the following for about 2 minutes, until very smooth:

1 cup coconut milk

2 cups water

1/4 cup yeast flakes

1 Tbsp. salt

1/2 cup raw cashews

1/4 cup pimentos

1 Tbsp. lemon juice

1/4 cup cornstarch

1 tsp. onion powder

1/4 cup plain soy milk powder

Drain macaroni and return to pot. Pour blended mixture into hot, drained macaroni and cook together until thick, stirring gently. Add any of the following if desired:

1-2 cups frozen peas

1 cup sliced mushrooms

1 cup sliced olives

Cover and let sit 5 or 10 minutes before serving.
