I have a kid with who prefers this sort of thing, so I often try to perfect something with the minimum ingredients.
Bread: flour, water, salt, starter Hamburger: beef, salt, charcoal grill Leek pie: flour, butter, water, leeks, gruyère, cream, salt
I recently started making fried chicken by marinating some chicken thighs in salt, sugar, vinegar brine for a day, coating it in literally just cornstarch, and frying it twice.
I will happily eat complicated food, but I think all the above are excellent and are all about quality ingredients and technique.
