Use about 1/5 of the olive oil (enough to coat the fish), and brush it all over the surface of the fish. Sprinkle salt and pepper all over the fish to your taste and preference. If you don't have kingfish belly, you can use a fillet or even skewered chunks of kingfish. Cook the kingfish belly for about 2 minutes on each side, until it flakes easily. Place the finger limes on the grill at the same time you do the fish. Cook the limes for about 1 minute altogether. Finger limes are native to Australia, and the pulp of the fruit is like little balls of caviar. If you can't find these limes, try substituting key limes instead. Slice the fennel very thin on a mandolin or with a sharp knife. You can also add the fronds of the fennel if you'd like. Toss the fennel with the juice and zest from 1/2 lime in a bowl, along with the rest of the olive oil. Add a few dashes of sea salt to the salad to flavor it. Cut the kingfish against the grain, and lay the pieces out on a platter. Spread the fennel salad out on top. Cut the finger limes along one side, and release the citrus pearls along the kingfish. If you're using key limes, dice the pulp and sprinkle it over the fish. "Against the grain" means cutting perpendicular to the lines you see in the fish, which make up the grain of the fish. Put leftovers in the fridge in an airtight container and consume them within 3 days.

Summary: Coat the kingfish belly in olive oil. Grill the fish and limes over medium heat. Create a fennel salad with the lime and olive oil. Slice and serve the kingfish.
