But TBH so many things can be cooked in 10 minutes.
Chicken breast cut into thinner slices marinaded in lime juice, seasoning, garlic, honey - on the BBQ done in around 12 minutes.

Pick up a steak form supermarket, 5 minutes to cook, 2 minutes to rest.

Even a quick stir fry can be done in 10 minutes or so. Quickly and roughly slice whatever veg I have lying around, into a wok with sesame oil, add some garlic and crushed chilies, tsp of Chinese 5 spice, soy sauce and if I have something like oyster sauce a dollop of that.
