I do like to eat something at breakfast.  If you want to get-up-and-go, I'm OK with a couple of granola bars and water. Those breakfast cereal bars are good, too, the kind with "milk" (like Honey Nut Cheerio Bars).  Maybe some Tang instead of plain water.

If you do want to boil water I like Grape Nuts Plus and Folgers dunk bag coffee.  Grape Nuts Plus prepares like instant oatmeal:

At Home
1/2 cup Grape Nuts
1 Tablespoon plus 1 teaspoon of powdered milk
1 heaping Tablespoon of dried fruit bits (Sunkist or Del Monte)
1/2 teaspoon sugar

Mix together in a lightweight plastic bag.  Tie shut.
     
In Camp:  Empty into bowl or cup.  Add 1/2 cup of boiling water.  Stir.  Serves one.
