My old backpacking meals looked like this.

Lipton (Knorr) noodles and sauce, they call for milk and butter, but you don't need it, i used to dump some powered milk in them.

Stovetop stuffing, again you don't NEED the butter

Powdered gravy mix (optional)

Dehydrated corn, peas, mushrooms (I used to make my own, frozen corn/peas are easy to dehydrate as are fresh mushrooms)

Dinner went like this, bring pot of water to boil, more than i needed for the noodles and sauce. Once water was boiling mix up my 'Bondo" which what we called it, much like the car body filler it was named for it "helped fill in the holes" in our appetite while the noodles cooked. This was instant potatoes , stove top, gravy mix and maybe some veggies in a bowl, add water and stir, very filling.

Eat that while preparing the Noodles and sauce.

Another good bet is instant pudding made with milk powder, make it in a ziploc or your cook pot and set it in a stream or lake to chill (weighted so it doesn't float away) this works in Michigan when you are always by the water. I've lived for up to two weeks on this before and there is enough flavors so you don't get bored, there are also rice dishes similar to the noodle ones.
