To start, cut the salmon into small ½" cubes and place them in a bowl with lime juice. Next, slice the mango, reserving a few small pieces, and cut the rest into ½" pieces. Add mango to the bowl of salmon, then season with 1 teaspoon each of salt, black pepper, and dried mustard. Stir to coat, then add capers and olive oil. Mix well, cover, and refrigerate for 1 to 4 hours before serving.
