Eggs, meats, and veggies?
This was my go-to breakfast before bp coffee: scrambled egg whites and sauteed greens (kale, spinach, collards, asparagus is awesome) slathered with hollandaise sauce (mix the raw yolks with melted butter, salt, and squeeze of lemon juice) And you could add bacon, sausage, ground beef etc. Chop up some avocado. I also ate sauerkraut with it.
...or ice cream
