Steam the sweet potatoes, peel, and mash them.
Add salt and flour to the mashed sweet potatoes and knead into dough.
Take an appropriate amount of dough, roll it into long strips, and cut into small gnocchi shapes.
Boil the gnocchi in boiling water until they float to the surface.
Add white basil pesto to a pan and heat over medium-low heat.
Add the boiled gnocchi to the pan and mix well with the sauce.
Serve on a plate and top with Parmesan cheese to taste.
