Prepare the Little potatoes according to the package directions. Set aside.
In a small bowl, combine the oregano, rosemary thyme, salt and pepper.
Place the chicken thighs in a bowl, sprinkle the oregano mixture over the chicken and toss to coat.
Heat 1 teaspoon olive oil in a large nonstick or ceramic skillet set over medium-high heat. Add the chicken and cook until browned, about 2 minutes per side. Transfer the chicken to a plate.
Reduce the heat to medium and add the remaining 1 teaspoon olive oil. Add the onion and cook until tender, 4 to 5 minutes. Add the garlic and cook for 30 seconds.
Add the chicken broth to the skillet and bring to a boil, scraping any browned bits from the bottom of the pan.
Return the chicken to the skillet, along with any accumulated juices. Cover and simmer until the chicken is cooked through, about 10 minutes.
Remove from the heat and stir in the spinach and cooked potatoes. Garnish with parsley. Serve.
