What a delicious summer dish! Here's a quick, cheap, & easy recipe from Martha Stewart's "Great Food Fast". (You probably already have a lot of the ingredients in your kitchen cabinet.)
1/4 cup reduced-fat sour cream
2 tablespoons lime juice
salt and pepper
1/4 small red cabbage thinly shredded (about 2 1/2 cups)
4 scallions thinly sliced (about 1/2 cup)
1 jalapeno chile, halved lenghtwise, one half minced
2 tablespoons olive oil
1 pound tilapia fillets (or other firm white fish) cut into 16 equal strips
8 flour or whole wheat tortillas
1/2 cup fresh cilantro leaves
1. In a large bowl, combine the sour cream and lime juice; season with salt & pepper. Transfer half the mixture to a container; set aside for serving. Toss the cabbage, minced jalapeno, and scallions with the remaining sour cream mixture. Season again with salt & pepper.
2. In a large nonstick skillet, heat the oil and remaining jalapeno half over medium-high heat; swirl to coat the bottom of the pan. Season the fish on both sides with salt and pepper. In two batches (starting with any larger pieces), cook the fish until golden brown on all sides, 5 to 6 minutes. Discard the jalapeno.
3. Warm the tortillas.
4. Fill the tortillas with slaw, fish, and cilantro leaves. Drizzle with reserved sour cream mixture.
