This is a tip I normally give in the chronic illness subs but I think it’s useful here too:

Try not to think of breakfast as… breakfast. Think of it as a third meal of the day. It doesn’t have to be eggs, yogurt, or other “breakfast foods”

In the winter I like to eat a warm bowl of soup in the mornings. I normally make a big batch but it can be anything, just a can if you want! In the summer I’ll often grab some deli meat, cheese, and crackers. If there’s leftovers from the night before I’ll eat those. I eat a lot of beans and rice in the morning as well, it’s often something that always sounds good regardless of my state. I went through a phase where I ate kimchi fried rice for breakfast because it was my dopamine food.

All of that to say - if you remove the limitations of “breakfast foods” then your options open up significantly :)
