What kind of food do toucans eat that i can get at a supermarket?

i built an avian room in my back yard with exotic tropical plants, hygromostats (i know it doesnt exist, i built one), thermostats, and 24hr video surveillance, the room is 50'Lx40'Wx15'H and it is outdoor, no predators like coyotes or bobcats can get in, and yes, it is going to be with more tropical birds like hyacinth macaws and scarlet macaws. now that i proved to all those tofu munching PETA members that its going to have a better life with me than in a zoo, i can get the answer that i need.... how can i give it a well balanced diet without having to order in exotic fruits from the amazon?
