Place potato flakes in a large bowl; stir in boiling water until blended. Stir in eggs. Add flour and salt all at once; stir just until combined. Divide into fourths; turn each onto a floured surface. Roll into 3/4-in.-thick ropes; cut ropes into 3/4-in. pieces.
Bring a large saucepan of water to a boil. Cook gnocchi in batches for 30-60 seconds or until gnocchi float. Remove with a slotted spoon. Place in a large bowl; top with sauce. Gently stir to coat. Sprinkle with cheese if desired.
Notes
Gnocchi with Meat Sauce
This dish from my mother-in-law is the Italian version of a meat-and-potatoes meal. I recently served it to friends who immediately wanted the recipe. —Karin Nolton, Ortonville, Michigan
