Preheat oven to 400°.
To prepare turkey, combine first 8 ingredients; rub over turkey. Place turkey on a broiler pan coated with cooking spray; insert a meat thermometer into thickest portion of a breast. Bake at 400° for 55 minutes or until thermometer registers 180°. Let stand 10 minutes before slicing.
To prepare couscous, bring orange juice to a boil in a small saucepan while turkey bakes. Stir in cranberries. Remove from heat; let stand 30 minutes. Drain cranberries in a colander over a bowl, reserving juice.
Heat oil in a large saucepan over medium-high heat. Add sliced garlic; saute 1 minute. Add onion and bell pepper; sauté 2 minutes. Stir in reserved juice, water, curry, 1 teaspoon salt, and broth; bring to a boil. Gradually stir in couscous; remove from heat. Cover and let stand 5 minutes.
Fluff couscous with a fork. Add cranberries, basil, cilantro, rind, and lemon sections, tossing gently to combine. Cut each turkey breast into 1/2-inch-thick slices. Serve turkey with couscous.
