Preheat the oven to 425°F. Toss the green beans in 1 teaspoon of olive oil, salt, and pepper, then spread them on a baking sheet and roast for 15-18 minutes until tender and slightly crispy.
Season the chicken breast with salt, pepper, and a pinch of garlic powder if desired. Heat a skillet over medium-high heat and add 1 teaspoon of olive oil. Sear the chicken breast on both sides until golden, about 4-5 minutes per side, until cooked through. Remove and set aside.
In the same skillet, add minced garlic and sauté for about 30 seconds until fragrant. Add the fresh spinach and cook until just wilted, about 2 minutes.
Stir in the artichoke hearts and light cream cheese. Mix well until the cream cheese softens and creates a light, creamy sauce. If needed, add a splash of water to adjust the consistency.
Return the chicken to the skillet, spooning the sauce over it, and let everything warm together for another 2 minutes.
Plate the chicken with a generous spoonful of the sauce, and serve alongside the roasted green beans.
