Divide filling between two flour tortillas and spread into an even layer all the way to the edge. Top each with half of the fresh basil leaves (leaving one edge bare so the tortilla can stick to itself). Press basil down slightly to adhere.
Use a serrated knife to gently cut tortillas into 1/2-inch slices. Between the two tortillas, you should have a total of 20-22 pinwheels (amount as original recipe is written // adjust if altering batch size).
