Fifteen minutes, one pan, and faster than a delivery. Toss the chicken in a teaspoon of cornflour before it goes in the pan; it is the restaurant trick that stops breast meat drying out.

This is the dinner for the night you were about to order in. It carries 51g of protein a serving, and the only thing that takes any time is slicing the chicken.
Chicken breast is one of the leanest proteins you can buy, which is also why it dries out so easily. The cornflour coating is a simplified version of velveting, the technique Chinese restaurants use, and it is the difference between chicken that is juicy and chicken that squeaks.
The salt is in the sauce, not the pan. A tablespoon of ordinary soy sauce carries well over 2g of salt, more than a third of the 6g adult daily maximum. That is why the recipe uses reduced-salt soy sauce, adds no salt anywhere else, and gets its flavour from garlic, ginger, vinegar and a little honey instead. Tamari tastes much the same and is usually gluten-free, but check the label: it is not automatically lower in salt.
Broccoli adds fibre and vitamin C, and the red pepper adds more vitamin C than an orange, gram for gram. Cooking the broccoli quickly, as here, keeps more of both than boiling it.
A serving is around 630 calories with the noodles, which suits a main meal after training. To make it lighter, halve the noodles and double the broccoli. It is also not gluten-free as written, because of the egg noodles; rice noodles and tamari fix that.
