Place the fish on a rimmed baking sheet; drizzle with olive oil and season with salt and pepper. Broil until the fish is lightly browned on top, 5 to 10 minutes, until the flesh is opaque throughout.
Meanwhile in a small bowl, mix the sour cream with 2 tablespoons of salsa.
Divide the fish evenly among the tortillas and top with shredded cabbage, sour cream and fresh salsa.
Notes
Any flaky, white fish may be substituted for Tilapia.
Using light sour cream is just fine.
Plain yogurt may also be substituted for sour cream.
Using fresh salsa is important..The chunks of tomato and onion are mixed with with lime juice and cilantro, and these flavors are a wonderful, easy addition to the tacos.
Shredded lettuce may be substituted for cabbage.
If preparing this recipe as GLUTEN FREE- just be sure to use corn tortillas that are GF.
