If you prefer a hot/cooked breakfast, try things that can be microwaved (like a refrigerated egg sandwich/wrap, or a portion of leftovers from dinner the night before) or that you can use a kettle to add hot water (like oatmeal), so you don’t have to worry about making time to wash any cooking tools. Or cold ready-to-eat foods (sandwiches, wraps, hardboiled eggs, overnight oatmeal), just keep something else you really really need in the fridge so you have to open the fridge in the morning to grab like, an important document or a pair of socks or your computer mouse or something, and your brain can more easily justify “well might as well grab that breakfast while I’m here”.
Also anything that you can eat/drink on your commute could also be a good idea.
Like tbh a good rule of thumb for any of these foods is how many steps they take to get ready (when you wake up) + how many bites they take to eat. If it takes more than 2 steps and/or more than 10 bites, it should be a food you really, really like to eat, or else it might feel more difficult in the morning to justify the effort/time it would take when you have other important things to do.
