Need Help Composing a Nutritionally Balanced (more or less), Shelf-Stable, Quick to Prep Hot Cereal

Hey guys, so I'm trying to be more health conscious about my breakfast (considering Cinnamon Toast Crunch every day is probably not the healthiest) so I tried to put together a well-rounded cereal bin where I can just scoop a half or whole cup, heat some milk, and put the two together. Now to do this, I did initially use AI to help, but I feel like I really need some human input so I'm starting from scratch. What I have right now is old-fashioned oats, peanut butter powder, freeze-dried strawberries and bananas, yogurt-covered raisins (big mistake, forgot that yogurt melts in hot milk), chia seeds, honey-roasted peanuts, and cinnamon powder.

Any ideas to add or remove anything to make this more well-rounded? I have no restrictions but I will not add protein or whey powder
