This is salty and sounds a bit nutty, BUT---

Try saving some of your dehydrated spaghetti sauce to eat as a leather. It can be an interesting and quick lunch if you layer or alternate bites with pepperoni and string cheese sticks. Or, take a pilot cracker and layer on sauce leather, pepperoni, and a slice of provolone or mozarella. If you have freeze-dried mushrooms and dehydrated olives, rehydrate those ahead of lunch to add. Zucchini chips are also good with this. You could have the dehydrated veggies ready and pick up the pepperoni and cheese along the way to reduce your pack weight at the beginning of your hike. Most gas stations and convenience stores have meat and cheese sticks, but not much for lightweight veggies beyond mashed potatoes or chips.
