Heat large covered saucepot of water to boiling over high heat. Add pasta and cook until just tender, about 2 minutes longer than label directs.
Meanwhile, in nonstick 12-inch skillet, heat oil over medium heat until hot. Add onion and cook 5 to 7 minutes or until tender and lightly browned. Stir in tomatoes with their juice, crushed red pepper, and oregano; heat to boiling over high heat, breaking up tomatoes with side of spoon.
Reduce heat to medium and cook 7 minutes to thicken slightly. Stir in shrimp, and cook 3 to 4 minutes or until shrimp turn opaque throughout. Remove skillet from heat; stir in chopped parsley and 1/2 cup crumbled feta.
Drain pasta; return to saucepot. Add shrimp mixture to pasta in saucepot and toss to coat. Spoon pasta mixture into large serving bowl; sprinkle with additional feta if you like.
