Prepare all of the ingredients. Start water boiling for pasta.
Add pasta to boiling water and cook as directed on the package. Drain in colander and rinse with cool water to arrest cooking process. Return to pot and set aside.
In a large bowl, add all shrimp ingredients except oil. Toss to evenly coat. (you don't need a thick coat on each piece, more of a light dusting)
In a large saute pan over medium high heat, add 2 tbsp of oil. Add shrimp - one by one - in a single layer on bottom of pan. Cook for 2-3 minutes then flip once. Cook another 2-3 minutes and remove from pan. Continue with remaining shrimp - adding more oil to pan as needed - until all cooked to crispy outer layer and pink inside.
In a small bowl combine remaining ingredients listed under noodles. Once noodles are done cooking, add 3/4 of scallions and sauce. Toss to coat.
In a shallow bowl, place a portion of the noodles. Then layer on a portion of shrimp, 8-10 pieces per person. Sprinkle with remaining scallions and sesame seeds.
