Canned salmon is pretty nutritious. I suggest making salmon has. Grate some potatoes, some carrots, some onion, chop some celery and let it soak in salt water for a while.
Then drain water, grate some cheese, and start frying the potatoes. When they start to get brown, add a half-a-can of salmon. The bones are pretty soft and a good source of calcium. When it is pretty close to being done, sprinkle the grated cheese and then add up to four eggs and cover on low heat until the eggs are covered.
