I'm not sure if I want to admit this....but, when I was younger I used to eat vanilla frosting with sliced american cheese. That has to be the most discusting thing...thankfully I didn't do it very often as we didn't have the frosting all the time.
Now, I have no idea what I'd consider the weirdest food I've had or still eat. I like ketchup on my pizza, and mayo on my fries. I'm sure I do a lot weirder stuff.
Someone said honey and bananas, I like peanut butter and banana sandwiches cooked up like you would grilled cheese and then drizzled in honey. So yummy.
