Cook the couscous according to package directions in a medium saucepan; stir in the golden raisins when the couscous is done and set aside.
Lightly moisten each chicken breast with a little water, then dredge evenly in the Italian breadcrumbs to coat.
Heat 2 teaspoons olive oil in a large nonstick skillet over medium-high heat, add the minced garlic, then add the breaded chicken.
Fry the chicken about 5 minutes per side, or until cooked through and no longer pink in the center; transfer to a plate and keep warm.
Meanwhile, zest one orange and squeeze the juice from both oranges into a small saucepan; add the orange zest and 2 tablespoons soy sauce and bring just to a gentle boil for 1 minute.
Stir the chopped green onions into the sauce, remove from heat, and set aside.
On each plate, arrange a handful of fresh spinach leaves, top with a portion of the hot couscous and raisins, place a cooked chicken breast on top, and drizzle with the orange-scallion sauce.
