Start by marinating the shrimp. In a bowl, combine the shrimp with Cajun seasoning, olive oil, salt, and pepper. Toss well and let it sit for about 15 minutes to absorb the flavors.
While the shrimp is marinating, prepare the corn and cabbage mixture. In a separate bowl, mix the shredded red cabbage, corn kernels, lime juice, cilantro, and a pinch of salt. Set aside.
Heat a large skillet over medium-high heat. Once hot, add the marinated shrimp in a single layer. Cook for 2-3 minutes on each side, or until the shrimp turn pink and are fully cooked. Remove from heat.
Warm the corn tortillas in a dry skillet or directly over an open flame for a few seconds until pliable.
To assemble the tacos, place a few shrimp on each tortilla, top with the corn and cabbage mixture, and add slices of avocado.
Finish with a drizzle of hot sauce if desired. Serve immediately.
Notes
Serve the tacos arranged on a large platter, with lime wedges and cilantro sprinkled around for a colorful and vibrant display.
