For the Baked Chicken Fingers:
Preheat oven to 400ºF.
Spray a baking sheet with cooking spray; set aside.
Cut each of the chicken breasts lengthwise into 4 to 5 strips. Place in a medium bowl. Add olive oil and stir to coat evenly; set aside.
In a shallow dish, mix together breadcrumbs, cheese, oregano, salt and pepper. Dredge the chicken in breadcrumb mixture to coat. Arrange on prepared baking sheet.
Transfer to oven and bake, turning once, until golden brown and cooked through, 12-15 minutes. Serve chicken fingers hot or at room temperature with marinara sauce, with Oven-Baked Curly Fries alongside.
