I've seen it all on the trail from backpacking trips with people trying to carry coolers filled with six packs and bacon, to people carrying very little and relying on the land for food. To each their own, and for me I eat like a champ!!!
My go-to meals on backpacking trips over the years have been the gourmet meals from Backpacker's Pantry. From breakfast to desserts they cover the gamut! I lean a little more on them for dinners though. Most of the Backpacker's Pantry meals are a serving size for two and loaded with much needed sodium to replace all that salt lost on a strenuous day of hiking. Loving me some Kung Pao Chicken! Most importantly, Backpacker's Pantry meals taste great too! If you need more incentive, look for the small details. The bottom of the package is a clear plastic so you can see the progression of your food as it prepares.
Some other quick and easy meal options I go to are; ramen noodles, MRE's, Easy-Mac, Mountain House, and homemade couscous mixes.
Always read the directions, make sure you have the proper equipment/gear to accommodate, and prepare accordingly. Be mindful of the foods you are eating and what it takes to prep the meals. Some other things that should impact your decisions are elevation, climate, seasons (time of year, not spices!!!), and nutritional value. Another thing to consider is water. Does your meal require it, such as dehydrated meals tend to? Keep this in mind and how you are going to procure water if needed.
