In a medium mixing bowl, combine the peeled and deveined shrimp with the Cajun seasoning, olive oil, and a pinch of salt and pepper. Toss well until the shrimp are thoroughly coated in the seasoning mixture.
Heat a non-stick skillet over medium-high heat. When the skillet is hot, add the seasoned shrimp in a single layer. Cook for about 2-3 minutes on each side, or until the shrimp turn opaque and are fully cooked (they should curl slightly). Once cooked, remove the skillet from heat.
In the meantime, warm the corn tortillas by placing them in a dry skillet over medium heat for about 30 seconds on each side or until they become soft and pliable.
To assemble the tacos, start by placing a generous layer of shredded red cabbage onto each warmed tortilla.
Top each tortilla with a portion of the cooked shrimp, a few slices of avocado, and a dollop of sour cream.
Finish by squeezing fresh lime juice over each taco and garnishing with a sprinkle of fresh cilantro.
Serve the tacos immediately, preferably with additional lime wedges on the side for an extra burst of flavor.
Notes
Arrange the tacos on a vibrant platter with lime wedges for a colorful presentation.
