Creating Purple Sweet Potato Gnocchi with Tahini Parsley Sauce is straightforward if you follow these simple steps:

1. Prepare Sweet Potatoes: Peel and chop the purple sweet potatoes. Boil in salted water until tender, about 15-20 minutes.
2. Mash and Cool: Drain the sweet potatoes and mash them until smooth. Let them cool for about 10 minutes.
3. Make the Dough: In a large bowl, combine the mashed sweet potato, flour, egg, salt, and nutmeg. Mix until a dough forms.
4. Knead Gnocchi Dough: Gently knead the dough on a floured surface until smooth, adding more flour if necessary.
5. Shape the Gnocchi: Divide the dough into smaller portions. Roll each portion into a long rope about ½ inch thick. Cut into bite-sized pieces. Use a fork to create grooves on each piece for better sauce adherence.
6. Cook Gnocchi: Bring a large pot of salted water to a boil. Add the gnocchi in batches and cook until they float, about 2-3 minutes. Remove and set aside.
7. Make Tahini Sauce: In a bowl, whisk together tahini, parsley, lemon juice, olive oil, salt, and pepper until well blended.
8. Combine: In a pan over low heat, gently toss the cooked gnocchi with the tahini sauce until well coated.
9. Serve: Divide the gnocchi among plates, and top with optional toasted pine nuts, additional parsley, or chili flakes.
