I bring salami, different cheeses, pepperoni, packaged rice, packets of tuna, nuts, dry fruit, tortilla's (quesadilla's or fish tacos if I'm fishing), ramen, asian ramen(Spicy), crackers, smoked salmon, jerky, candy bars, granolla bars, and I will bring a few Mountain House's. I will also bring powdered gravy, garlic, salt, pepper, hot sauce, etc. for seasoning.
I also like bringing Crystal Light packets of Fruit Punch, Pink Lemonade, etc. Nothing like having ice cold lemonade in the morning, along with a cup of coffee. Also, if your forced to drink interesting water the Crystal Light makes it more bearable.
