Begin by preparing the dough. In a mixing bowl, combine almond flour, coconut flour, psyllium husk powder, and salt. Mix them thoroughly to distribute the ingredients evenly.
Slowly add water to the dry ingredients, stirring continuously until a dough forms. If the dough is too dry, add a little more water, one teaspoon at a time, until the desired consistency is reached.
Place the dough between two sheets of parchment paper and roll it out into a rectangle, about 1/4 inch thick. Remove the top sheet of parchment paper.
In a small bowl, mix together the chopped sun-dried tomatoes, basil, nutritional yeast, garlic powder, and onion powder.
Brush the surface of the dough with almond milk, then evenly spread the sun-dried tomato and basil mixture over the dough, leaving a small margin at the edges.
Carefully roll the dough into a tight log, using the bottom sheet of parchment paper to assist you.
Once rolled, use a sharp knife to slice the log into 12 equal pinwheels.
Arrange the pinwheels on a serving platter and lightly brush the tops with olive oil for a glossy finish.
Serve immediately or store in an airtight container in the refrigerator for up to 3 days.
