Cook pasta according to the box instructions. When done reserve 1/2 cup pasta water and drain.
While that is cooking, add all the ingredients for the vegan nacho cheese recipe into blender. Follow directions for blending. Set aside.
Chop up your onion, pepper, and garlic.
In a large skillet, over medium heat, add some vegan butter and let melt.
Add in onion and pepper and let cook for 2-3 minutes.
Add garlic and cook for 1 minute.
Add in vegan crumbles and let cook for 4 minutes.
Pour in half the vegan cheese sauce and cooked pasta. Stir around until very well combined.
If sauce needs thinned a bit, add in a splash of the reserved pasta water. If cheesier pasta is desired, add more of the nacho cheese sauce. Taste and add salt and pepper if desired.
Sprinkle some vegan parmesan on top if desired.
