Marinate the fish in 1 teaspoon of olive oil and salt. Let it sit for 15 minutes.
In a small pot, steam the asparagus until slightly tender.
Meanwhile in a frying pan heat up 2 tablespoons of olive oil.
Add fish turning once until it is cooked through. Depending on thickness, this could be 3-4 minutes.
In a separate bowl, add the cooked asparagus, mango, scallions, and the juice of the lemon. Mix well.
When the fish is finished cooking, add the mango mixture on top. Enjoy!
