Step 1: Bring a large pot of water to a boil.
Step 2: Shell and devein the shrimp. Slice the mushrooms and coarsely chop the scallions.
Step 3: Add the pasta to the boiling water and cook until al dente, 10 to 12 minutes.
Step 4: Meanwhile, in a serving bowl, beat the egg. Stir in the half-and-half, Parmesan cheese, parsley, anchovy paste, mustard and pepper. Set aside.
Step 5: In a large skillet, warm 2 tablespoons of the olive oil over medium-high heat until hot but not smoking. Add the mushrooms and garlic and stir-fry until the mushrooms are almost limp, about 5 minutes.
Step 6: Add the remaining 1 tablespoon oil and the shrimp, stir-fry for 2 minutes. Add the scallions and stir-fry until shrimp turn pink about 2 minutes longer.
Step 7: Drain the pasta in a colander. Add the hot pasta to the beaten egg mixture and toss to cook the egg as well as coat the pasta. Add the shrimp-vegetable mixture and toss to distribute evenly. Serve hot.
