Anything healthy. I'm trying to reduce our grain intake, so I try to distract them from toast and processed cereal. I do make oatmeal, oatmeal bars, or muffins sometimes. Lots of scrambled eggs with cheese & veggies. Yogurt. Peanutbutter on toast, crackers, or a spoon. Dinner leftovers. Homemade chicken broth. Cheese. Sweet or regular potato home fries or potato pancakes.
There is nothing wrong with fruit and hardboild eggs. I like to cook a lot at once and heat up. I also like baby led weaning, where you rarely make child specific food, they get what you get. I hate that people think they should feed dd "kid" food, kd, hot dogs, nuggets ie processed junk.
french toast sticks with syrup , eggs and toast, cheerios /cereal with milk, breakfast sausage links, fruit. Some days he will ask for leftover mac n cheese or soup or even cold pizza. All fine by me as long as he eats! I should look into the microwaveable pancakes or make a big batch and freeze them as he asks for them almost daily.
