I usually go with a mix of products depending on how long im going for, I usually spend only around 2 nights at a time when wild camping.
I'm also a quick walker and like to eat a lot, my usual menu goes like this.
Breakfast - instant oats with jam / trail mix or freeze dried meal such as eggs n ham.
Lunch - snack lunch, usually couple of bifi rolls, energy bars, cup o char.
Tea/Supper - again either a freeze dried meal (home made or store bought) and snacks.
trail mix while im on the go.
Snacks of trail mix, (nuts, fruit and m&m's) and flapjacks / oatcakes (even cadburys brunch bars are great) , Bifi rolls and ofc chocolate hobnobs 
2 nigh stay usually has
3 x 300g trail mix
6 x flap jacks / energy bars.
6 x bifi rolls (or pepperamis if im out of bifi) - (bifi roll is like pepperami in wheat bread roll)
2 x instant oats
1 x MH egg n ham breakfast.
3 x MH meals / home made dehydrated meal.
pack of mixed drinks, tea, coffee, chocolate, iso's and jam packets, salt pepper sugar ect ect.
weighs in around the 2 kilo mark for the 3 days, 2 nights but has a nice mix of fat, protien and carbs and i also like to have a little more than i need when it comes to food.
Usual solo cookset is a simple jetboil and spork, but ill take my multi fuel trangia if im going with a couple of people, but then thats a different story all together as ill take more dry ingredients and do more proper cooking.with more proper cooking involved but then ill usually source half the ingredients on the move such as bacon n eggs, sausage and steaks ect ect but i will carry instant mash, noodles, pasta ect ect.
I can also reccomend MRE's tho they are helluva expensive nowadays, but a couple stripped down can make a huge difference to variety.
