When the family members who are dieting really want a no-fat meal, there is a way to do it with an exceedingly small amount of fat. I would actually not count the "fat" I added as fat, and see if you can identify it in the following list of ingredients.
Two large heads of broccoli. (Wash, cut stems away from florets, but in pot ready to steam. But don't steam them yet.) Set aside.
In a small pot put half a cup of water, a tablespoon of dry chicken broth (chicken bouillon powder), a diced red bell pepper, a grated carrot, one minced garlic clove (or more) and/or grated fresh ginger. Let boil briefly, stirring, then let simmer.
Arrange slices (about 5 oz each or around 200 grams) of salmon in a dish (rinse first). Grate fresh pepper over the fish fillets. Then pour the veggie-broth mixture over the salmon.
Put the salmon in the oven, which you've preheated to 220 at least--put the oven tray near the broiler and set the oven to whirling heat.
Start the broccoli steaming at the same time.
Fifteen minutes later, you can eat.
Where is the fat? A teeny, tiny bit in the chicken powder. Less than in a tablespoon of olive oil
