Pretty sure anything in a can may be eaten as is. My go to's are beans and a bag of corn chips or alpha-gettis. Gourmet dining it is not
I usually take a small jar of peanut butter and a spoon. Bagels or crackers are good.
Last year I learned how to make old fashioned hard tack. I will take a supply of that on trips from now on.
Speaking of cans and beans.
Last month (February) I did a challenge where in I only ate beans for a month. Breakfast, lunch and supper.. nothing else.
It can (pun intended) be done.
