My personal favorite:
Crack two eggs, and add a splash of milk into the bowl, whisk, and add sea salt, fresh ground pepper, and crushed garlic (or garlic powder if you prefer).
Then coat the Tilapia in it.
Get a bag of pistachios, shell them, and then crush.
Sprinkle the crushed pistachios on the dipped tilapia, and bake at 350 degrees. after about 5 minutes, pull it out, and coat it with a marmalade of your choice, anything citrus based is lovely. From there, Bake until cooked to your preference, and enjoy!
