In a small bowl, whisk together the low-sodium chicken stock (or vegetable broth), low-sodium soy sauce, rice vinegar, Hoisin sauce, brown sugar, Sriracha, minced garlic, and grated ginger. Set this mixture aside.
In another small bowl, combine the cornstarch with a tablespoon of water to create a slurry.
Heat the un-toasted sesame oil (or canola oil) in a wok or large skillet over medium-high heat. Add the shrimp in a single layer and cook for about 2-3 minutes on each side until they turn pink and opaque. Remove the shrimp from the pan and set aside.
In the same pan, pour in the sauce mixture and bring it to a gentle simmer. Stir in the cornstarch slurry and cook for an additional minute.
Return the cooked shrimp to the pan, tossing them in the sauce until evenly coated. Cook for an additional minute to heat through. Serve over rice or noodles.
