Brush chicken breasts with oil then season on both sides with salt and pepper. Heat a large, oven-safe skillet over medium-high heat, then spray with nonstick spray. Add chicken and cook for 2-3 minutes a side, or until golden brown (does not need to be cooked all the way through.) Remove to a plate then set aside.
Turn heat down to medium, then remove skillet from burner and let cool for 1 minute. Add marinara sauce (use caution, as sauce may splatter a bit,) parmesan cheese, and dried basil to skillet then stir to combine. Nestle chicken halves into sauce mixture then return skillet to heat, place a lid on top, and cook for 10 minutes, or until chicken is cooked all the way through.
Heat a large pot of water then season with salt and add pasta. Cook until al dente then drain and set aside.
Remove skillet from heat then top chicken with sliced mozzarella and broil until golden brown and bubbly.
