In a large skillet, melt 2 tablespoons of butter over medium heat. Add the diced potatoes and sauté for about 10-12 minutes, or until they are golden brown and tender. Stir occasionally to prevent sticking.
Once the potatoes are cooked, remove them from the skillet and set aside.
In the same skillet, add the remaining 2 tablespoons of butter. Add the diced chicken breasts and season with paprika, thyme, salt, and pepper. Cook for about 6-8 minutes until the chicken is browned and cooked through.
Add the minced garlic to the chicken and sauté for another 1-2 minutes until fragrant.
Pour in the chicken broth and bring to a simmer, allowing the flavors to meld together for about 3-5 minutes.
Return the sautéed potatoes to the skillet and mix everything together well.
Fold in the fresh spinach and cook until wilted, about 2 minutes.
Taste and adjust seasoning if necessary before removing from heat.
Serve hot and garnish with freshly chopped parsley.
