Complex carbs (like oatmeal) with some, but not a lot of protein. Sandwiches are ok, if you use whole grain bread and not a ton of meat and cheese. Protein is hard to digest and too much will make you feel like crap. What is too much depends on you. PB&J's work well. Whole wheat pasta is also good. Simple carbs burn up too fast and cause your blood sugar to spike and then it crashes causing you to feel tired and fatigued. The "what to eat" thing really varies from person to person and requires some experimentation. What works for me, may not work for you.
It sounds to me like you are just not consuming enough calories for the amount of riding that you are doing. You may want to eat a little more and carry a flask of something like Hammer Gel. Take a shot periodically to keep your energy up and to use in case of the dreaded bonk.
Another thing to consider, especially in the summer, is electrolyte replacement. I sweat like a pig in the summer. I've been on rides where I've had to fill my Camelbak as many as 3 times. I put electrolytes directly into my water to make sure that they are getting replenished.
Hope this helps.
