Prepare the slaw by tossing shredded cabbage with lime juice and a pinch of salt. Set aside.
Season the fish fillets with cumin, paprika, salt, and pepper.
Heat olive oil in a pan over medium heat and cook the fish for 3-4 minutes per side until golden and flaky.
Warm the corn tortillas by lightly charring them in a dry pan or over an open flame.
Assemble the tacos by placing cooked fish into each tortilla, topping with cabbage slaw, and drizzling with the creamy sauce.
Garnish with fresh cilantro and serve with extra lime wedges.
