• Heat the vegetable oil in a deep pan or skillet over medium-high heat.
• Season the shrimp with salt and pepper.
• Dredge the shrimp in the cornstarch, making sure they're evenly coated.
• Fry the coated shrimp in batches until they are golden brown and crispy, about 2-3 minutes per side. Place the fried shrimp on a paper towel-lined plate to drain excess oil.
• While the shrimp is cooking, dice your tomatoes and slice your green onions.
• Prepare the Bang Bang Sauce. In a separate bowl, whisk together mayonnaise, sweet chili sauce, rice vinegar, sriracha sauce, and sugar. Taste and adjust the spice level with more sriracha if needed. Set the sauce aside.
• In a large bowl, drizzle the crispy shrimp with the prepared Bang Bang Sauce. Toss the shrimp to coat them evenly with the sauce.
• Garnish the Bang Bang Shrimp with chopped green onions and tomatoes.
• Serve your homemade Bang Bang Shrimp as an appetizer or over a bed of white rice or fresh lettuce.
