Pretty much any meal while I am camping is great! I'm away from work and the house (so I am not bothered with all things I "could be doing"), and just relaxing.
We go up to a friends Vermont hunting cabin a lot. I was on the deck with him one morning having coffee. Cheap, basic coffee. That tasted great. We both commented at how everything seemed to taste better up there - similar to camping, everything just seems to taste better....
For breakfast while camping, my wife many times will make buttered, toasted bagels using a fry pan in the morning. It is just something we usually only do while camping, and it always seems to taste great!
Best, most memorable meal? Probably two:
Back to our friends with the Vermont cabin... we also have camped with them a lot. One time we met them up at Acadia, Maine, at Blackwoods campground. They put together a "seafood boil" -- when done, they basically poured it out onto a table covered in newspaper. We just dug in, eating for what seemed like hours. Fantastic food, fantastic location, fantastic friends.
Second. Camping out with same family, plus another, at a campground in Rhode Island. Plus a few kid's friends. Must have had about 15 people total maybe. One morning, we all got together for breakfast. Pulled a couple grills together. Cooked sausage, bacon, biscuits, potatoes, eggs, cheese, toast, ham, steak, and other food, including leftovers from other meals. We have a couple pictures of food piled on grills and tables. Was a fantastic breakfast feast with good company! Even managed to actually fill up teenage boys!
Good camping!
