In a covered pot, and using no salt or spices, combine:
1 cup water
1 chicken breast
1/4 cup rice
Simmer 20 minutes and add:
3 whole carrots
1/4 pound green beans
Simmer 10 minutes longer.
Blend or process the meat with enough of the cooking broth to make it moist.
Mash the carrots and then the beans
Store separately in individual servings in the freezer sealed in plastic sandwich bags, or in a plastic ice-cube tray, which must be bagged and tied.
Defrost a meal at breakfast, so it's ready to heat for lunch.
