Powdered eggs generally are not good.  I buy mine at my local food CoOp.  I don't remember the brand but it come in a quart, plastic jar.  That jar lasts me years.  Powdered eggs are great as a substitute for fresh eggs in baking or making a "regular" pancake mix into a "add water only" mix (adding powdered milk as well).

However, I have found one way that powdered eggs are good, and that is as a breakfast burrito.  Here is my recipe:

Breakfast Burrito
     
1/2 cup powdered eggs
Spices (1 teaspoon chili powder blend, 1/4 teaspoon oregano, etc.)
1/4 cup dried beef (or substitute hard salami)
4 teaspoons dried bell peppers
1 Tablespoon dried minced onions
2 teaspoons dried celery
Some hard cheese
2 or 3 Tortillas
     
At Home: Put powdered egg & spices in one bag.  Mix together peppers, onions, and celery in another bag.  

In Camp: Combine the vegetable mixture with 3/4 cups of water and set aside for 15 minutes.  Add powdered egg and meat. Let stand for another 5 minutes.  Fry adding cheese near the end so that it melts.  Roll equal portions in each of the tortillas and topped with salsa (poached from your local Taco Bell).
