Dunno if it's sins but...
I'm a dunker, oreos, cookies, donuts all of it goes in coffee or milk, always.
Buffalo sauce or hot sauces on everything. Even in ramen.
Mayo on anything bread, sometimes just mayo on bread for a snack.
Chips on sandwhiches.
Ketchup on eggs.
Sometimes if I eat store brand bread like the white bleached stuff that's not good for you I'll dip it in Dr.Pepper or Coke, it's an interesting flavor.
Microwave nachos of tortilla chips, grated cheese and sometimes lunch meat thrown in the microwave.
Microwave quesadillas of tortilla and cheese thrown in the microwave.
...everything in the microwave. I can't cook to save my life.
