Heat 1 tablespoon oil in a large skillet over medium-high heat until hot.
Add 1 pound peeled and deveined shrimp to the skillet and cook, stirring occasionally, until the shrimp are opaque and fully cooked through, about 4-5 minutes.
While the shrimp cooks, combine 1/4 cup hoisin sauce and 1 tablespoon low sodium soy sauce in a medium bowl.
Pour the sauce over the cooked shrimp and toss to coat evenly.
Cook for an additional 1-2 minutes to heat the sauce and finish coating the shrimp.
Serve immediately, garnished with green onions and sesame seeds, if desired.
