Bring a pot of salted water to a boil and cook the chickpea pasta according to the package instructions until al dente.
Season the chicken breast evenly on both sides with sea salt, black pepper, and garlic powder.
Heat the extra virgin olive oil in a medium skillet over medium-high heat.
Add the chicken to the skillet and cook for 5-7 minutes per side until golden brown and the internal temperature reaches 165°F.
Remove the chicken from the pan, let it rest for 3 minutes, then slice it into thin strips.
Drain the pasta, reserving two tablespoons of the cooking water to help emulsify the sauce.
In the same skillet or a large bowl, combine the cooked pasta, sliced chicken, basil pesto, sundried tomatoes, and fresh spinach.
Toss everything together until the spinach is slightly wilted and the pasta is coated in the vibrant green sauce.
