I like real food for breakfast. When we were younger we used to stay with my grandparents on a lake and we'd have panfried fish for breakfast (if we caught any the day before). Trout, bass, bullhead/catfish. That was good. I like smoked fish too - salmon, mackerel, trout. With bagels/bread and cream cheese, or with scrambled eggs and toast. I loved breakfasts in Japan because we always had plain rice, miso soup, tomatoes and mayonnaise, and sometimes a little bit of leftover dinner. I like leftovers for breakfast as well. And sweet baked goods are welcome occasionally , too (even cake and pie).
But most mornings I rely on cereal...sigh...
