Place the cashews, salsa, pumpkin puree, nutritional yeast, cumin, salt, and water in a blender and blend on high until smooth.
Sprinkle with chopped cilantro and serve immediately with tortilla chips.
If you want to serve this hot, pour the smooth queso into a pot over medium heat for 3 – 5 minutes. Whisk continuously until it is warmed through. If it gets too thick, add 1/4 cup water to thin it out.
