Just soak in lukewarm or cold water for at least 6-8 hours and cook thoroughly. (The longer they soak in water the more tender they get.)

When will your freeze-dried food expire?
The manufacturer guarantees the minimum shelf life of 25 years from when the food was made. To find the manufactured date, look at the label on the can. There should be a code similar to this one below:
8034 b2 19
All you need to look at is the first set of numbers (8034) - that is the date code in Julian format. So in the example above, it was made on the 34th day of 2018, which is February 3. 25 years from this date gives you the minimum of how long it will last.
Note: Since it is a long-term storage, the shelf life will depend on the conditions under which you store the food.
