I second Elif's suggestion about salmon filet. If you have a Costco nearby, check their frozen section for salmon filets. They sell frozen Norwegian salmon filet in a 5 pound bag, and there are approximately 15-18 filet in the bag (it's sold by weight). Each filet is in a separate pouch so you can thaw what you need. I drizzle olive oil, salt, pepper, or I use butter and herbs, and bake, uncovered, at 300F for 12 minutes, no longer than that. The filets turn out moist, perfectly cooked, never overdone. I serve with basmati rice or potato vegetable pucks from Ikea. Salmon has excellent nutrition, omegas, and is easily digestible. Any fish, really, would be excellent for you right now while your pouch is a youngster. By using different store bought sauces that you like, or fresh herbs, you can give it a different taste. If you use fresh herbs, tuck them under the fish so they aren't burned, which makes them slightly bitter.
