Sometimes I don’t want to eat eggs and oatmeal for breakfast at all. Do you have any other nutritious and long-lasting alternative to eat in mornings?

Finding healthy food you enjoy over long periods is challenging. I find it helps to have a few go to breakfasts you can cycle through every week.
Yogurt with frozen fruit and granola
Sliced cheese, dates, cured meat and bread
A protein shake blended with frozen fruit
