I would put in Sinangag/Garlic Rice, but that goes beyond breakfast anyway. These items are generally considered to be breakfast food though...

• Ginisang Itlog (Eggs with tomato, onion and garlic)
• Corned Beef (Palm Corned Beef in particular, but any kind if sunog)
• Cereal (with or without milk)
• Spam (like Harold says, I f***in love Spam!)
• Longganisa (from Cavite, with the little jeweled chunks of taba)
• Daing (the little kind, not the huge ones)
• Hotdogs (Ginisang hotdogs, in particular.)
• Toast with butter and jam
• Vienna Sausages
• Tinapa (Mmmmmmmm.)
