This simple recipe is from Christian and Aaleiyah Martínez, owners of Taco Libre, a food truck in Kauai, Hawaii. El Restaurante writer Natalia Otero interviewed Christian (click here to read the interview) and he gave her this recipe afterwards. He says, "These onions are killer on tacos or just with chips."
