Combine nutritional yeast, soy milk powder, oats, sun-dried tomatoes, onion powder, garlic powder, cumin, and a few light dashes of smoked paprika and chili powder in a blender.
Pulverize until you have a smooth, homogenous, flour-consistency but not overly powdery like powdered sugar.
Add more sun-dried tomatoes for a stronger tomato flavoring.
Store mix in a dry, airtight container.
Multiply out the mix as much as you want!
To make cheese whiz: In a medium sauce pan, whisk together ¾-cup mix (not packed tight—spoon it in gently) and1 cup COLD water until well combined.
Cover and heat over low until thick and cheesy—it happens quick, keep an eye on it.
Taste and adjust (adding a pinch of salt or 1/4 tsp yellow or white miso paste and/or a squeeze of fresh lemon juice if you have it. You might also want to add a drop or two of agave or a pinch of sugar to the mix).
