This meal for 8 is one of my favorites. I've adapted it from a recipe in Backpacker magazine (2000). It's time consuming to make at home... but super easy to cook in the field. I prepare it more as a thick mush. It's an amazing taste and it's filling!

Ingredients:
(The following ingredients made about 1-1/2 qts (wet) more then I needed.)

1) 10 lbs. Russet potatoes - diced small
2) 40 oz. Spinach - chopped
3) 24 egg whites
4) 10 minced garlic bulbs
5) 2 teaspoons ground black pepper
6) 8 teaspoons fresh thyme chopped fine
7) 3 teaspoons salt
8) 1-1/2 cups milk (use low fat next time)
9) 5 tablespoons Vegetable oil
10) 3 cups finely grated parmesan cheese (next time use low fat shredded cheese)

(1) Cooking at home:

(1a) Cook diced potatoes in a water; lightly boil for 10 minutes or until tender. Drain and rinse in cold water. Put aside. Cook spinach until done by placing in a large pot w/ 1 cup of H2O - about 5 minutes from the time the water starts to boil; drain. Whisk the eggs, salt, garlic, pepper, milk and thyme in a large bowl. Stir in potatoes and spinach. Heat oil in a large saucepan, add fritatta mixture, and lightly simmer for about 15 minutes. Weigh and record the Fritatta in quart increment before going to step #3.

(1b) Weigh and record each quart of fritatta so you can compare the "wet/cooked" weight with the "dehydrated" weight; the difference between the two is the amount of water to hydrate with;
1-qt. = 2-lbs.)

(1c) Fill a large Pyrex baking dish midway with the fritatta, sprinkle with cheese, and place under a broiler until the cheese begins to lightly brown. Spread the fritatta thinly on dehydrating trays w/ solid inserts.

(1d) Made 7 Qts. Wet (15 lbs)

(1e) Dehydrated on 8 trays for 23 hours at 145 degrees

(1f) Made 4 Qts dry (2-LB/6-oz)

 

(2) Vacuum Seal::

(2a) Divided the deydrated fritatta (1-LB/3-oz) into two pouches

(3) At Camp:

(3a) Place contents of each pouch in separate pots (4 qt. Size)
(3b) Add 2-1/2 to 3 Qts water. Simmer until soft. Add more water for desired texture.
(3c) Should feed each of the 8, 3 cups of wet.

(4) Field Test Results:

(4a) I only used 2-qts. H2O.
(4b) To make a thicker frittata, next time I'd bring some flour to add.
(4c) I did not make desert as folks were very full
