My boys love this fish recipe. It is, in face, their very favorite meal ever. I think it's the lemon herb seasoning they love so much. I prefer the flavor of the lemon herb to the lemon pepper, bit either will work. I find it at Wal-Mart. This is a super fast, super easy, and reasonably healthy meal.
4 Tilapia fillets
2-4 T soy sauce (or Bragg's amino acids... a good substitute with less salt, and lots of good minerals for you... start with just 2 T and adjust according to your taste)
lemon herb seasoning (or lemon pepper)
2-4 Tbsp. butter
1. In a large saucepan (one that will fit all 4 fillets at once) melt about 2 Tbsp. butter. Add the soy sauce to the saucepan and let the butter and soy sauce just cook and thicken for about 30 seconds to a minute.
2. Sprinkle both sides of the fish fillets very liberally with lemon herb seasoning. Place them in one layer in the saucepan.
3. Saute in butter and soy sauce in skillet until done, turning once.
4. Serve hot, pouring the extra liquid and scrapings from the pan over your fish.
As an alternative, I like to put my fillets in tin foil packets and cook them on the grill... they're even more tender that way.
