Pack the dry ingredients in a quart freezer bag and the buns in a separate bag. You can use potato rolls instead of mini slider buns, both work well. Pack the cheese with it.
Bring ¾ cup water to a boil and let sit for a minute. Pour in, seal tightly and put in a cozy for 15 minutes. Thinly slice the cheese and divide between the buns.
Stir well and season to taste with black pepper and salt, if desired. Divide the mixture on the buns and serve.
