Place the pine nuts in a small, dry skillet over medium-low heat and toast for 2-3 minutes until golden and fragrant, then set aside.
Bring a medium pot of salted water to a boil and cook the potato gnocchi according to package directions, draining once they float to the surface.
Season the chicken breast with sea salt and black pepper on both sides.
Heat the extra virgin olive oil in a large skillet over medium-high heat and sear the chicken for 5-6 minutes per side until cooked through and golden.
Remove the chicken from the pan, let it rest for 2 minutes, and then slice into bite-sized strips.
In the same skillet, add the baby spinach and cook for 1 minute until just wilted.
In a small bowl, whisk together the basil pesto and plain Greek yogurt to create a creamy sauce base.
Reduce the skillet heat to low, add the cooked gnocchi and sliced chicken back to the pan, and stir in the creamy pesto sauce until evenly coated.
Divide the gnocchi into a bowl and garnish with the toasted pine nuts before serving immediately.
