if your meat is not rehydrating well, then it does not have enough surface area (too large a particle). I don't dry a fully made meal. I dry a sauce and then grind it up into a powder in the food processor. Then I combine the powdered sauce and carb base in the bag. This helps with rehydrating with just boiling water and no need to cook. There will be a few small crunchy bits in the corners of the ziplock or vac bag, but they are small and eat fine.
