Place fish on rimmed baking sheet; drizzle with olive oil & season with salt and pepper. Broil until fish is lightly browned on top, 5-10 minutes, until flesh is opaque throughout.
Meanwhile in a small bowl, mix sour cream with 2 tablespoons fresh salsa.
Divide the fish evenly among 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.
