So what do you pack? what can you cook with the simplest of tools? My advice, pack a large frying pan, a medium or large pot, tongs, a spatula and a spoon.
And what can you cook with that?
Breakfasts are simple, you have cereal, eggs and bacon, pancakes even if you do them small and one at a time.
Dinners, now there you can have fun. There is smothered pork chops, loaded baked potatoes, fish fillets, my favorite chicken rice a roni, loaded mac n cheese, spaghetti, not-lasagna casserole, chicken angle hair pasta. And when you don't want to cook inside, because she is moving to a beach community there is always the option of grilling burgers and brats, bbq chicken.
And don't forget the s'mores for dessert!
