I mean the one you do when you want something easy to do, but not when you're tired at the point you microwave a frozen-meal, or just cut down a piece of cheese and put it in a bread
In a saucepan caramelize some onions (or at least until translucent), then add a package of ground beef and heat until cooked through (optionally spice) then throw some cheese (ideally a provolone or other neutral cheese) on top until it's melted... shovel all that into a baguette and enjoy a munkwich.
I know you clarified that they can just be to translucent, but it's hilarious to me that the first step to a lazy meal is to spend 45 minutes caramelizing onions.
Caramelization is a specific chemical change to the sugars in the onions. Brown =/= Caramelized and will affect the flavor significantly so you really shouldn't cut corners.
If I'm commiting the time to do it I just make sure to make as much as I can fit in my pot.
Laziness, for me at least, is about effort more than time - caramelizing onions (once you're familiar with the process) can be done on autopilot in fifteen minutes or less. But for the above recipe, five minutes should be plenty.
But true caramelization on onions is still like 45-60 minutes of constant attention. It's not difficult, but it does require a lot of time and effort. You're not getting a caramelization in 15 minutes without a pressure cooker and even then they taste like nothing so what's the point?
Unfortunately kind of limited on options for Korean butchers, living in the middle of corn fields, but I make a trip down to the Asian market an hour away once in a while to grab all that stuff. Will check on that!
