In a medium skillet, heat the oil over medium-high heat. Once hot, add the pineapple, red onion, and a pinch of salt. Reduce heat to medium, cover partially, and let soften—5 minutes, stirring occasionally. Reduce heat to medium-low and add the soy sauce, mirin, and honey. Cook 8-10 minutes more, until softened, and darkened in color. Taste for salt, and keep warm until ready to serve.
