I don't usually take a stove since I mostly tour by myself and can live just eating sandwiches, fruit, salad, etc. that I can grab at almost any grocery store in the area I tour. I usually carry a bag of oats and that's for breakfast or even a quick snack (I eat it raw with milk/juice like museli). Things like cereal bars are also good snacks as they are around 200 calories each and that's about what I couple of hours depending on the speed and terrain and they don't mind getting squished in a pannier. I don't cook a lot at home in the summer either so it's not unusual for me to eat museli for supper as well. A bag of GORP type trail mix can also add to the museli as well as roadside fruit and the like if you're in an agricultural area. I also eat out at any restaurants that look like they serve food I like too... a tour is a holiday for me so I don't mind the expense of eating out. If anything I've often got too much food with me considering how close I usually am to towns and stores.
