I get my MH at Costco too. Great deal. Ramen noodles aren't gourmet, but they're light and pack a lot of cals. They're not too bulky IMO. I always have some of my dried fruit along, and often some jerky. Granola bars or oatmeal packets for breakfast.
I like packing the gatoraid powder (usually in the single serve, and usually generic) to put in the water.
Oh...I also like hitting bulk food stores and getting dried banana chips.
