Preheat oven to 400 F
Add the warrior bread mix to a large bowl.
In another bowl, whisk together the water, egg whites, and vinegar.
Pour the liquids into the bread mix and stir well to combine. Knead for about a minute, then allow to rest for a few minutes.
Line a baking sheet with parchment paper.
Split the dough into 6 equal parts. Form a 4 inch disk with each piece of dough and place them evenly on the baking sheet. Top each one with some sesame seeds and press them into the dough to help them stick.
Bake for about 40 minutes until cooked through.
Remove from oven, allow to cool, and slice in half.
