In a Vitamix or high-powered blender, combine the cashews, water, buffalo sauce and salt, blend well. Pour into a bowl, cover, and place in the fridge for about 2 hours to help the sauce thicken.
Slice the veggies and set aside. When the cream has thickened, spread a thin layer onto each tortilla, top with a thin layer of veggies, then roll and slice into bites.
Place in the fridge until ready to serve. They'll last about 3 days in the fridge.
