Heat oven to 450 F. Place the cauliflower and onions on a baking sheet lined with parchment paper.
Drizzle the vegetables with the vegetable oil. Season with salt and bake for 35 to 40 minutes, or until golden brown and easily pierced with a fork.
In a blender, combine the roasted cauliflower and onions, nutritional yeast, garlic, L&B Southwest Trail Dust Seasoning, turmeric powder, smoked paprika, ground mustard, apple cider vinegar and avocado oil. Blend on high until smooth, 3 to 4 minutes.
Transfer the queso to a serving bowl. Garnish with smoked paprika and the cilantro and serve with L&B White Tortilla Chips.
