Nacho Doritos style Cheese Powder

3/4 cup cheese powder (cheddar popcorn seasoning, or the powder for mac and cheese, or Parmesan Alfredo pasta sauce powder which is mostly parm powder)
1 1/2 teaspoons ground rock salt (pink Himalayan)
1 teaspoon onion powder
1 teaspoon garlic powder
1 teaspoon chili powder
3/4 teaspoon paprika
3/4 teaspoon black ground pepper
1 teaspoon Accent (MSG)
1 teaspoon tomato powder (pulverized dried tomatoes, dry tomato soup mix)

This is REALLY spot on. That's it. Enjoy!

UPDATE:
Have been working on this every weekend since posting.
Turns out I wanted something other than REALLY spot on.
This is now what I'm using:

• 1 oz nacho cheese popcorn seasoning
• 1 tbsp Zesty Italian dressing powder (copycat)
• 1 tbsp dill
• 1 tsp celery salt
• 1 tsp garlic powder
• 1 tsp onion powder
• 1 tsp ground coriander
• 1 tsp ground rock salt
• 1 tsp MSG

Vegans, sub out nutritional or Brewer's yeast for the cheese. Weirdos like me, add a teaspoon or two of ground coriander, switch out smoked paprika for paprika, add a teaspoon of sugar, a teaspoon of citric or malic acid powder if you want extra tang. It's pretty tangy already. I think next batch I might go heavy on the tomato powder.

For nacho pretzels, I've been using half a stick of butter and half a cup of neutral veg oil, tossing into bag of pretzels and shaking up with the nacho powder, then drying in 220F oven for an hour, tossing every 15 minutes until it's all crispy again.

Oil by itself does not work, it won't stick. My theory is the water in the butter binds with the spice mix and bonds to the pretzels as they dry out.
