Rice is a cereal and therefore a valid breakfast food. Fry last night's rice with some chopped veg and garlic salt for a nutritious and easy breakfast.
Fried rice keeps better than steamed. Make it once a week and massively reduce your time/resources spent on the daily. The secret is the extra sauce with 45% spicy mayo, 45% teriyaki sauce, and 10% Worcestershire sauce or similar Roman garum-like fermented fish sauce. Put that on top of fried rice to make a killer meal.
Fried rice is basically just eggs and rice at the simplest form; breakfast.
