1. In a small mixing bowl, combine the ranch dressing and sriracha. Reserve refrigerated. 2. In a separate mixing bowl, combine shrimp, salt, black pepper, red pepper flakes, and lime juice. Toss to combine. 3. Heat a saute pan over medium high heat until hot. Add olive oil, then the shrimp, and saute until pink and cooked through (about 2 to 3 minutes), turning often to cook evenly. 4. To assemble tacos, place about 4 warm shrimp into each tortilla and top with 1 tbsp. diced mango and 1 tbsp. diced onions. Drizzle with sriracha ranch dressing and sprinkle with chopped cilantro. Serve with lime wedges to be squeezed over top.
The spiciness of this dish can be adjusted by adding more or less sriracha to the ranch dressing.
