To make the tropical salsa: Mix all ingredients except oil, grouper and Cajun spice. Let sit while you prepare the grouper.
To make the grouper: In a cast iron frying pan, heat olive oil until smoking. Coat both sides of grouper with Cajun spice. Place coated grouper in pan. Cook for 2 to 3 minutes per side (depending on thickness) until done. Transfer grouper to a serving dish, placing on top of mixed greens. Spoon Tropical Salsa on top of fish.
