What are some standard, common dishes that you have changed or adjusted to make them even more tasty?

I’m not talking about exotic stuff liked truffled rutabaga tagine with tomato citrus gravy, I’m just talking about regular, everyday stuff that most people know about and eat. You know, like tacos, spaghetti, meatloaf, potato salad, deviled eggs or whatever else that most people like.

What do you do to common dishes to spruce them up and give them that wow factor?

I made a killer macaroni and cheese the other day using Trader Joe’s Caramelized Onion Cheddar Cheese, and the addition of fresh mushrooms sautéed with shallots, and topped with panko bread crumbs. I must admit, it was da bomb!

What have you made, lately, that transformed an ordinary, common dish into an extraordinary dish?
