Tilapia Tostadas with Roasted Corn Relish

I love fish tacos. Keeping the tortilla flat allows for more stuffing. This was to be made with Tilapia, but I had catfish in the freezer, so I substituted. This dish yields four servings. We have one serving left. They were very filling, Jim only ate for 2. It is noted that corn tortillas contain about half the fat and calories and ¼ the sodium of the same sized flour tortilla. Gee I actually prefer something that is better for me.
Ingredients:
½ C reduced-fat sour cream
¼ C green salsa
Cooking spray
1C yellow corn kernels
¼ C finely chopped red bell pepper
¼ C finely chopped red onion
11/2t minced seeded jalapeno pepper ( I used jalapeno peppers in a jar. They have more heat like the ones we used to get in CA.)
¾ t salt, divided
1 C diced peeled avocado
2t fresh lime juice
1 ½ # tilapia fillets, cut into 2” pieces
1/4t freshly ground black pepper
1/3C yellow corneal
1T canola oil, divided
8 (6”) corn tortillas
1 C packaged slaw
Directions:
1. Combine sour cream and salsa.
2. Heat a large nonstick skillet over medium-high heat. Coat pan with cooking spray. Add corn, bell pepper, onion, jalapeno and ¼ t salt to pan; sauté 5 minutes, stirring occasionally. Remove mixture from pan; wipe pan clean with paper towels. Combine the avocado and juice; toss gently. Stir avocado mixture into corn mixture.
3. Preheat broiler.
4. Sprinkle fish evenly with remaining ½ t salt and black pepper. Place cornmeal in a shallow dish; dredge fish in corneal. Heat 1 ½ t oil in pan and over medium heat. Cook half the fish at a time. Do not crowd the skillet; 3 min. side one and 2 min. side two.
5. Repeat oil and the remaining fish.
6. Coat both sides of tortillas with cooking spray. Arrange tortillas in a single layer on baking sheets; broil 2 minutes on each side or until crisp. I did 4 at a time in batches.
7. Place 2 tortillas on 4 plates. Arrange 2 T slaw on each tortilla. Divided fish evenly among tortillas; top each serving with equally divided corn relish and the sour cream mixture.
Each serving is 470 calories. Jim served a Viansa Sauvignon Blanc It was very good.
