Preheat oven to 400 degrees.
I’m a small bowl combine the garlic powder, Italian seasoning, salt, paprika, pepper, and 1 tsp of the onion powder. Mix until all combined. Set aside.
Pat the chicken dry. With a basting brush, brush 1 tbsp of the olive oil on the chicken. Once brushed, sprinkle the seasoning evenly over each of the chicken pieces. Put in the oven and bake for 20-25 minutes (if using bone-in thighs, add about 10 minutes to the cooking time).
While the chicken bakes, heat the remaining olive oil in a medium skillet. Add the garlic and cook for a minute until fragrant.
Add the green beans, season with salt, pepper and remaining onion powder. Cook for about 10 minutes until soft.
Remove the chicken and serve hot with the beans.
