I usually add potato chips or Doritos to PBJ’s, ham & cheese, sloppy joes, and hamburgers. IMO, it adds some extra flavor to the sandwich, along with an added crunch as well.
The most common food, drink, and condiment combos (IMO) include: dipping fries in milkshakes, using different flavors of milk for cereal, using more than 1 condiment, and mixing all holiday food together (Thanksgiving).
On an extra note, a “Hurricane” is when someone uses every single sauce that’s available. This usually happens at Subway or similar restaurants.
My wife thought it was weird that I “dipped” Fritos in cream cheese. It’s pretty much the only thing we ever used cream cheese for growing up. It’s delicious!
I make cranberry sauce with zero added sugar by just simmering cranberries with a splash of water. I then add a few tablespoons of this cranberry sauce to a dish of plain Greek yogurt. Delicious!
A good, sturdy cheddar cheese makes a fine sandwich with quite a range of jams/jellos/preserves. Some you might like to try: strawberry, raspberry, blackcurrant, cranberry, apricot, apple.
Cottage cheese works well with Indian pickles like lime or brinjal.
I always get a Bacon Egg and Cheese sandwich with mayonnaise. I was introduced to this exact sandwich probably in the early 1980’s by a dude who worked for my dad, and I don’t think I have ever seen anyone else ever order a BEC with mayonnaise except for me and him.
A guest at a party I attended brought a salad made from watermelon, supremed grapefruit and oranges, fresh jalapeno & mint, tossed in a balsamic based dressing. I think there was something else dark in color, maybe blueberries or grapes? Anyway, I took a small, just-being-polite token portion and quickly went back for more. I was astounded at how well it all came together.
I sometimes stir a few spoonfuls of hot giardiniera into cottage cheese with a small pinch of oregano.
