In a small mixing bowl, add water to the raw cashews and leave them to soak for 4 to 6 hours.
After soaking, drain, rinse, and set aside the cashews.
Clean and chop the red pepper and small onion, set aside.
In a medium sized pan, saute the red pepper, onion, minced garlic in oil until the vegetables slightly brown or caramelize. Set aside to cool.
Add the cashews, oil, tomato paste, mustard, pasta sauce, and all the seasonings to a high speed blender.
Next add the cooled sauteed vegetables to the blender.
Measure the vegetable broth in a large measuring cup and add the cornstarch, mixing until there are no lumps.
Start the blender on the lowest speed and slowly add the vegetable broth mixture to the blender.
After the broth has been added, continue to increase the speed to the highest speed.
Continue at the highest speed for about 1 minute.
Now slowly decrease the speed until you get to off.
Check the consistency of the cheese, if not creamy enough continue blending until smooth.
After the cheese is well blended and smooth, pour into a medium sauce pan.
Cook on a medium heat for about 5 to 10 minutes, this will thicken the cheese.
After 5 to 10 minutes, remove from heat, set aside to let the mixture cool.
Pour any left over cheese into a container with a lid and store in the refrigerator.
