I bring bagels, cut in half, toast in frying pan. I buy Brie in single serving pots ( 10 in netting) to put on them. All available in local grocery store. This year, due to 10 day trip, we'll be bringing freeze dried meals from Happy Yak out of Quebec which includes breakfast egg omelet with cheese and egg omelet with fine herbs.
Have never tried happyyaks before, but we hear good things about it. They have a website if you want to know more.
On shorter trips we bring ( unwashed) eggs to Make scrambled eggs. You can also buy shelf stable bacon ( pre fried, does not need refrigeration) in most grocery stores, walmarts etc.
