I dip my potato chips in my baked beans instead of using a spoon. When I was little we kids all used to eat Mayo and sugar sandwiches. I was a fan of pickled beet sandwiches, just layer the pickled beets on the white bread with mayo. My mom and I like tomato sandwiches, a think layer of juicy, beefsteak tomato on white bread with mayo and lots of salt and peper. We kids also used to make our PB&J with a layer of potato chips inside. Last, but not least, my brother and I mixed our peas into our applesauce and called it Green Martians in Fog. We ate it that way for years.
Ironically, several things other people ate that seemed weird to me are now pretty standard like, dipping carrots in peanut butter, ranch dressing on fries or ranch dressing on pizza. I also always mix mayo and bbq sauce for any bbq meat and the fries. I think I got that from Red Robin.
