Pat your fish filets dry with a paper towel and season lightly with sea salt and pepper on both sides.
Heat your oil in a large skillet and sear the mahi mahi until beautifully golden on both
sides and fish is flaky throughout, around 2-3 minutes per side. Set aside on a plate.
In the same preheated skillet add your butter, and saute the garlic for 30 seconds.
Add the juiced lemon, capers, and chili flakes.
Allow the sauce to bubble for a minute or so, then nestle in the seared mahi mahi.
Spoon sauce over your fish filets.
Add the lemon slices, then remove from heat and garnish with freshly chopped parsley.
Enjoy it while it's hot.
