Preheat the oven to 400°F and season the tilapia with lemon pepper seasoning. Bake the tilapia for 10-15 minutes, until the meat turns opaque and flakes easily with a fork.
To assemble the tacos, top the tortillas with the desired amount of salsa, followed by about 1/2 tilapia fillet per tortilla.
Drizzle each taco with the cilantro lime crema, and garnish with chopped cilantro and sliced green onion.
