I discovered roasted seaweed at the little hiker store in the hostel in Lone Pine. After doing the math, I calculated it had a whopping 165 calories per ounce (6 per gram)–pretty good for vegetables–although I assume, most of the calories come from the oil they are roasted in. 
I eat them like chips, but the worker at the store said she crumbles them in anything she is cooking–contributes salt, oil, and veggies to any meal.
The packaging is quite bulky; I emptied them all into a baggie and threw away the packaging.
I think it may be cheapest to buy from Costco.
I like them too and buy them in bulk from Costco … I think I will use them on the PCT in 2017 🙂
Yeah, good price at Costco. Good luck on your 2017 hike!
Hi, I’ve found your blog helpful, thanks for sharing what you’re learning. I was intrigued by the calorie density of the seaweed you found, but I keep coming up with a different number:
12 oz of seaweed/5 servings=2 oz/serving.
20 calories/serving = 10 calories/1 oz.
Am I missing something?
Yeah, it’s 20 calories per 3.4 grams for a serving of roasted seaweed. There are 28 grams in a ounce. So that is roughly a little more than 8 servings per ounce. 20 calories X 8 = 160 calories for an ounce of roasted seaweed. Or another way to figure is divide 20 calories by 3.4 grams = 5.88 calories per gram. 5.88 X 28 grams = 165
