Begin by preparing one batch of Apple Arugula Sumac Salad—it takes just 6 minutes! Set it aside.
Hold the mango upright with the stem facing up. Slice about 1 cm from the center on both sides to remove the mango cheeks. Score the flesh in a grid pattern without cutting through the skin, then scoop out the cubes with a spoon or push the skin outward to release them. For the middle section, peel the skin and cut off any remaining flesh around the pit. In a bowl, combine the mango, green jalapeño, cherry tomatoes, brown onion, lemon juice, sugar, and salt. Mix well and set aside.
Prepare the crispy shrimp station. In a small bowl, crack an egg and whisk until well mixed. In a medium bowl, combine panko crumbs, smoked paprika, onion powder, garlic powder, cumin powder, and salt. Mix well. With one hand, dip a shrimp fully into the egg. Transfer it to the panko mixture, using the other hand to coat it well. Be gentle to ensure the coating adheres. Set the coated shrimp on a plate and repeat for all shrimp. Let them rest for 15 minutes to help the coating stick better.
Heat oil in a frying pan over medium-high heat. Once hot, fry the shrimp in batches (do not overcrowd the pan). Fry for 2-3 minutes per side or until golden brown. Remove and set on a plate.
Prepare the soft tortillas (see Notes). Place an equal amount of Apple Arugula Sumac Salad at the base of each taco, followed by Spicy Mango Salsa. Finally, top each taco with three Crispy Shrimp/Prawns.
Serve and consume directly.
