Heat 1 tbsp coconut oil in a skillet over medium heat, and add 2 or 3 tilapia fillets, making sure to not overcrowd the skillet. Cook for 2 minutes.
Flip tilapia, and add ½ tsp ginger, ¼ tsp garlic and ⅓ tsp shredded coconut on top of each fillet. Let cook for 1 minute. Add 1 tbsp coconut aminos on top of fillets and cook for another minute. Flip fillets one last time, cook for 1 more minute and remove from heat.
Repeat step 3-6 with remaining fillets.
Top with green onions and fresh lime juice if desired, and serve right away.
