I think pancakes are a great meal idea for hiking trips. You can buy the mix that only requires water (watch out for the ones that require oil and egg).

I'm making pancakes at home right now and I mixed up 1 cup of mix with 2/3 cup of water. I weighed 1 cup of mix at 159g (5.6oz) which makes a pretty decent amount of food. It looks like I'm going to get 6 decent sized pancakes out of this.

That might be a bit light for 2 people but it's a feast for one. You'd probably want about 3/4cup/person for a nice meal. Maybe less for a smaller person.

UPDATE: My wife and just ate the pancakes. I had 4 and she had 2, we are both full but could probably cram 1 more down each. This confirms my suspicion that 3/4 cup (120g or 4.2oz) is a good amount per adult male. Besides the mix, you'd probably want an ounce or two of maple syrup and a bit of oil to cook it with. Total meal weight is likely around 7oz.

I'm not sure how good pancakes are nutritionally, but under 1/2 lbs for a hearty meal that is cheap and easy to plan is great.

It looks like this meal doesn't provide a ton of calories. The pancakes seem to be around 300-400 calories and that rises by a few hundred more with the syrup depending on how much you slather on.

One cool thing about pancakes is that they're a great way to use berries that you forage.

They also make great "bread" for snacks during the day - cook, cool and carry in a clean sandwich bag. Then slather on nut butter!

4.2 oz. of dry mix should be ~420 Cal. or a bit more if the water-only mix has some fat incorporated to make up for the oil you don't add. Good rule of thumb I learned is carbohydrates (sugars, starches, grains, pasta, flour, crackers, etc) = 100 Cal./oz.; protein = 100 Cal./oz.; fats and oils = 240 Cal./oz. I figure if the food is pliable (like bread, tortillas, salami, or jerky) there's usually some water content, so the calorie density is a bit less than whatever the dry components are. Nuts are great, tho'--high oil content, so sunflower seeds for example are 176 Cal./oz. I'm still doing a lot of reading in these forums and elsewhere to try to get a good nutritional balance, in addition to high calories.

I don't cook in the backcountry (just boil and rehydrate) but pancakes with pinenuts and huckleberries fried in ghee sounds mighty tasty.
