So far here are Quinn's food rules as I have determined them to be.
Ice cream must be mixed: peach ice cream - no good, peach and strawberry ice cream - good*. Entree's must be separate: hot dogs good, pasta good, hot dogs on top of pasta- no good. Lunches have to be finger foods, no utensils, and not messy (eliminates most leftovers, even pizza). Breakfast is limited to yogurt, cereal, pancakes or bacon; french toast, eggs, sausage, everything else is excluded. Cakes / desserts must be chocolate or have chocolate chips.
