Preheat your grill or a skillet over medium-high heat.
Season the salmon fillets with olive oil, salt, and pepper.
Place the salmon on the grill or skillet, skin side down.
Cook for about 4-5 minutes, then flip and cook for another 3-4 minutes until fully cooked.
Remove salmon from heat and let it rest for a few minutes.
While the salmon is resting, warm the corn tortillas in a dry skillet for about 30 seconds on each side.
Flake the cooked salmon into bite-sized pieces.
Layer the tortillas with shredded cabbage, followed by the flaked salmon.
Add diced tomatoes and avocado on top.
Garnish with chopped cilantro and serve with lime wedges on the side.
