My hiking (also biking) fare is very similar to yours, with some variations.

I generally make up my own oatmeal packets, using rolled oats, with powdered non fat milk, nuts, dried fruit, and whatever. Much cheaper than the silly Quaker packets - a victory of packaging over price. For variety, I will make pancakes (if I am packing a skillet).

Lunch is usually just a series of snacks, similar to yours. I like Tanka bars - they are mostly protein and really tasty, but they ain't cheap. Nuts are hard to beat for lightweight nutrition.

Dinners include instant potatoes with beef jerky and assorted vegetables or pasta with whatever, typically lots of cheeses.

I am a tea drinker, but when I do coffee, I really like Via. In cold weather, it is great to eat hot Jello. Combine hot Jello with your oatmeal for an unusual breakfast.
