Stir the ingredients for the sauce in a medium-sized bowl or cup until thoroughly combined. Do the same for the corn starch slurry in a separate small bowl. Set both of these aside until later.
Partially cook the shrimp: Add 1 tablespoon of neutral flavored oil to either a large wok or walled pan. Place this over high heat so that the oil begins to smoke. Toss in the shrimp and stir fry them for roughly a minute or until they just start to turn pink. Then quickly remove them from the wok/pan and set them aside on a plate.
Stir fry the hard vegetables: Add another 2 tablespoons of neutral flavored oil to your wok/pan and let it heat up until smoking. Next toss in the minced ginger and stir fry it for 20 to 30 seconds, making sure that you don’t burn them. Then add the bell pepper, zucchini, and jicama to your wok/pan and stir fry these ingredients for 2 to 3 minutes or until they have become slightly softened.
Finish the dish: Add the snow peas into the wok/pan along with the prepared sauce that you made earlier. Stir everything together and let the sauce come to a boil. Then add the partially cooked shrimp along with the green onions, and continue to stir fry everything for another minute. Finally pour in roughly half of the corn scratch slurry and stir to combine with the sauce. If you prefer your sauce to be thicker then add the rest of the corn starch slurry and stir to combine.
Quickly transfer the Hunan shrimp to a large plate, garnish with the chopped cilantro, and serve immediately. Enjoy!
