Preheat oven to 400°F
Add 1 tbsp butter and 1 tbsp olive oil to a large skillet and cook over medium-high heat. Once the butter begins to foam, place the chicken in the pan, skin side down.
Let the chicken cook for approximately 6 minutes or until the skin is a deep golden brown, then flip and place on the middle rack of your preheated oven for 20 minutes.
Remove the chicken and return the skillet to the stove. Add chicken broth, lemon juice, and raise the heat to high to bring to a boil.
Once the broth is boiling, add the couscous. Cook the couscous for 8 minutes, stirring frequently to prevent the couscous from sticking to the bottom of the pan
Reduce to a simmer and mix in salt, pesto, and spinach.
Add back the chicken to get it nice and warm, then turn off the heat and serve
