Wash scallops in cold water, pat thoroughly dry, and cut into pieces about 3/8 inch thick.
Cook garlic in olive oil over medium heat until light gold. Add parsley and hot pepper, stir once or twice, then add scallops and 1 or 2 large pinches of salt.
Turn heat up to high and cook about 1 1/2 minutes, stirring frequently, until scallops lose their shine and turn flat white. Do not overcook. If they shed a lot of liquid, lift scallops out with a slotted spoon and boil down the juices, then return scallops and turn them over quickly. Turn off heat.
Toss thoroughly with cooked drained pasta. Add bread crumbs, toss again, and serve at once.
