In the book Maniac Magee, what does Maniac eat?

Because he is essentially homeless, Maniac Magee pretty
much eats whatever he can get his hands on. His most favorite food is Tastykake
butterscotch Krimpets, and, oddly, he is allergic to
pizza.

Among the things that Maniac eats in the book are
spaghetti at the Pickwells', "carrots, apples, and day-old hamburger buns" at the deer
shed at the Elmwood Park Zoo, and a bite of Mars Bar Thompson's candy bar which was
offered as a challenge. When he initially is living with the Beales, Maniac tries pizza
for the first time in his life, and breaks out in "round, red blotches" all over. At the
East End Fourth of July block party, he feasts on grilled chicken and ribs and
sweet-potato pie, and at Cobble's Corner, he has orange soda and is introduced to what
would become his favorite food, butterscotch Krimpets.

When
Maniac, near starvation, is rescued by Grayson at the zoo, the first thing he eats is
some chicken noodle Cup-a-Soup. He also has a zep, which is like a hero sandwich, and
more Krimpets. When Grayson takes the unbelievably hungry boy to a diner, Maniac
"wolf(s) down meatloaf and gravy, mashed potatoes, zucchini, salad, and coconut custard
pie," and one morning, in the bandshell, the old man brings him "an Egg McMuffin and a
large orange juice." On Thanksgiving, Grayson and Maniac cook a magnificent dinner on
two hotplates and a toaster oven. Their bill of fare is "a feast of roast chicken,
gravy, cranberry sauce, applesauce, SpaghettiOs, raising, pumpkin pie, and, of course,
butterscotch Krimpets."
