Scoop out the pulp from the passion fruit and press through a fine sieve. Reserve the juice (about 1 teaspoon). Coat the shrimp in olive oil and sear in a skillet on high heat until cooked through. Transfer to a stainless steel mixing bowl, add the passion fruit juice and the remaining ingredients, and toss well to combine.;
Prepare the salsa and set aside. Coat the Ahi steaks with peanut oil and season with salt and pepper. Heat a dry cast-iron skillet and sear the Ahi over high heat for about 15 to 20 seconds each side for rare (about 1 minute each side for medium-rare). Place the steaks on serving plates and spoon the salsa over the tuna, letting the juices from the salsa run onto the plates.;
