I bought a box of these at Costco, but it looks like I won't be able to finish them, so I'm offering some. Expiration date: 2025/10/18. ◼︎Cooking Instructions Take them out of the outer bag and heat them in the microwave. The official instructions say 2.5 minutes at 500W, but in my microwave, 3.5 minutes at 500W worked well.
