can i subsist on protein bars and PBJs?

ive always struggled with food while backpacking. i dont like actually cooking anything in my cookpot cuz it gets dirty and nasty. i only use it for boiling water. ive tried the ziploc freezer bag trick where you put your ramen, knorrs or whatever into the ziploc then add boiling water but most of the time that is really gross and hard to eat. PBJs and protein bars are two things i know i can eat every day without getting super sick of eating them and i dont need to cook or boil them. i can see myself being one of the hikers who goes stoveless for sure. will i be the only hiker carrying ~10lbs of peanut butter, jelly, bread and protein bars? hahaha
