Here’s some ideas:

• peanut butter or eggs with cheese on whole grain toast
• Soft boiled or fried eggs over rice with soy sauce and kimchi/hot sauce. The goey yolk makes the rice creamy. Can make the rice and boiled eggs the night before to save time in the morning. You can also marinade peeled boiled eggs in soy sauce and spices overnight
• Add some fresh fruit, whatever is on sale/in season
