Layer ingredients into clean, wide-mouth mason jar in the order listed above. Shake to settle contents.
Place new canning lid on top of jar. Using wide-mouth attachment for a FoodSaver, vacuum seal lid onto jar following instructions from your FoodSaver manual. (You can also insert an oxygen absorber before putting on lid if you'd like.)
Remove vacuum attachment and put ring on. Tighten by hand, but don't over tighten.
Label and date. Store in cool, dry location.
To cook:
Empty contents of jar (minus oxygen packet if present) into large skillet. Add 3 1/2 cups water and bring to a boil over medium-high heat. Reduce heat and simmer for 12-15 minutes, stirring frequently. Remove from heat and let sit 3-5 minutes to allow sauce to thicken.
Notes
You can substitute chicken TVP for the freeze-dried diced chicken.If you are having a hard time finding freeze-dried vegetable mix (do not use dehydrated), you can substitute freeze-dried corn or peas or a combination of both!
