In a small bowl, combine seasoning for chicken - paprika, garlic powder, onion powder, salt and black pepper.
Pat dry chicken breast and sprinkle seasoning all over on both sides.
Add vegetable oil to skillet, bring to on medium high heat.
Once skillet is heated, sear chicken breast for a couple of minutes on both sides until both sides are golden brown.
Remove chicken breast from skillet. Slit chicken breast lengthwise 3/4 of the way through (avoid cutting chicken into two pieces).
In a large bowl, combine all spinach and artichoke mixture ingredients. Mix to combine. (See Note 1) Mixture should be chunky and thick.
Stuff each piece of chicken breast with 2-3 tbsp of spinach artichoke mixture. Do not overstuff - it will spill out when baking if it's too full.
Bring chicken back to oven safe skillet. If skillet cannot be heated in the oven, bring chicken to a large casserole dish.
Bake chicken for 30 minutes, or until it is cooked through. If checking with a meat thermometer, the thickest part of the chicken should reach 165℉ to be considered fully cooked.
Remove chicken from oven. Serve and enjoy!
Notes
Note 1: Pat dry artichoke and make sure it is dry before adding to mixture. If using frozen spinach, make sure to pat dry to remove excess water. It will look like there is a lot of spinach, but once combined with the other ingredients, it will shrink.
