"So I'm curious what sort of no-cook low maintenance breakfasts people like to bring."
+1 to the granola/powdered milk suggestion, above. Also, if you have access to a Trader Joe's, check out the Sesame Crepes. Tasty, ~140 calories/oz, cheap, and pack well. Trader Joe's also has an excellent assortment of trail mixes, nuts, dried fruit, and granola, all at very reasonable prices, and all of which can be used in a no hassle breakfast. They're a great source for backpacking food. Have fun up here. Glacier Peak Wilderness is a great place to backpack.
