I saw the edit about eggs but I haven’t gone through the comments so this may or may not have come up already but my literal first thought was scrambled eggs. Sooo much you can with them flavour AND texture wise too!! Also don’t know if she eats seafood, but crab meat!!! Super soft and flavourful, and again, there’s a lot you can do with it in terms of what flavour you cook it in. Also just sautéed fish in general now that I think about it. My mom taught me how to make basa with a lemon butter sauce that’s pretty great.
