Using this Go Native vegetable curry is super easy. First, find a pot and fill it with water. Bring the water to a boil. Then, take the meal pouch and place it into the boiling water. Let it sit there for 6 minutes. After that, you can open the pouch and start enjoying your meal. You can also add mashed potato or rice to the curry to make it more filling. As for the shelf life, check the manufacturing date on the pouch. These meals can last up to 2 years from that date. There's no need to worry about dehydration as these are ready - to - eat meals. Just store them in a cool, dry place until you're ready to use them.
