I tend to switch to healthy eating when I have very little time to cook. It sounds a bit inconsistent, I know.
These steamed veggies are a good example. I just put chopped carrot, cauliflower, green beans and brussels sprouts into my steamer and get back to work.
If some of the veggies are frozen, they require half the time. So I just add them a little later.
The only unobvious ingredient is a pumpkin seed oil: everything tastes better with it.
