Chicken breasts are stuffed with flavorful roasted red peppers, gooey mozzarella cheese, and fresh baby spinach for the easiest twist on stuffed chicken!
Pat chicken breasts dry and cut a slit in each about 2/3 through. Season with salt and pepper and dredge each breast in flour. Set aside for a moment.
In a medium skillet over medium high heat, saute garlic, roasted red peppers, and spinach in 1 tablespoon olive oil until spinach is wilted, about 5 minutes.
In a separate skillet, heat remaining 1 tablespoon oil and butter over medium-high heat until shimmery. Sear chicken on both sides 2-3 minutes per side until golden brown. Transfer to a large plate.
Fill each chicken breast with roasted red pepper mixture and a slice of mozzarella cheese, using toothpicks to secure. Place chicken breasts on a baking sheet and bake at 375F 20-25 minutes or until chicken registers 160F. Remove toothpicks before serving and enjoy!
