Ohh, my grandma did the similar thing for my mom back in the Soviet times
She made a sweet soup with noodles. Basically, boiled them in milk and then added honey. Tried it myself, really tasty
Omelette is a wise choice! It's quick to prepare and protein-rich 😁 Cooking up a porridge or some oatmeal is a good idea too, because it's quick and gives you the calories you need.
