1) Buy one of these:

2) Make a home-cooked meal, something 'saucy'.
3) Line a bowl with plastic wrap.
4) Make sure your bowl will fit easily inside the pot you use to boil water in (there must be enough room to completely cover your frozen meal with boiling water).
5) Pour your meal inside the plastic wrap, and wrap it up completely.
6) Freeze until it's not longer viscous, or too soupy. (This step may not be necessary if your meal isn't too soupy to begin with.
7) Take your meal out of the bowl, slide it into one of the plastic bags from t the FoodSaver, and remove the plastic wrap that it was in the freezer with.
8) Vacuum seal your meal.
9) Shape the meal into a round, flat 'ball" (see step #4 above) and put in a bowl. You are better to make two smaller meals than one big one, otherwise, it will take too long at cooking time.
10) Freeze the item.
When at camp:
1) Boil water.
2) Put your meal in the boiling water
3) In approximately ten minutes time, remove your meal from the water, and cut the top off.
4) Eat right out of the bag.
5) Laugh at your partner who is muddling his way through a carboard MountainHouse crap meal while you are enjoying a nice salmon and dijon cream sauce with green beans.
6) Lick spoon clean.
7) Use previously boiled water for herbal tea.
8) Pack up bowl and cleaned spoon.
9) Throw your plastic bag in the garbage (they are reusable, if you are so inclined)
10) Laugh at your other partner who is now cleaning up his fry pan and pots and pans in -10 degree weather with freezing fingertips.
11) Warm sake on the stove
Breakfast:
Fry up hash browns and sausages.
As long as it stays freezing, you can make one of these for each day. They can be heavy, but the tastes far exceed the weight.
