Ive been down this path.

2 Hidden valley ranch packets, 1 tbsp onion powder, 1 tbsp garlic powder, 1 tbsp salt, and 1 tbsp paprika if you want to try to make it yourself. It tastes exactly the same to me.

You can paint the tortilla chips with canola oil and sprinkle the seasoning on. Or just drink the seasoning with a straw if you want to.
