It's actually what he ate every day for lunch. The man loved cottage cheese with fresh fruit that he had flown in from California with a side of grain cereal or wheat germ. He also had his coffee beans flown in for his breakfast which was always fresh orange juice, half a grapefruit, cold cereal and skim milk, and coffee. The guy was a huge fan of fresh produce and loved salads. Dinner was his big meal, and like our current impeachment in process, he was a fan of meatloaf.
Edit: There is also a rumor he like ketchup on his cottage cheese. Staff have denied it but the rumor persists.
Anyway, more food pics.
