In a medium saucepan or pressure cooker, combine the jackfruit, beans, pico de gallo, and water. If you are using a saucepan, heat the jackfruit mixture over medium-high heat until it begins to boil. Reduce the heat, cover the saucepan, and simmer for 20 to 25 minutes. If you are using a pressure cooker, cover the pressure cooker, bring to pressure, cook at low pressure for 3 minutes, and then use a natural release.
