Pat chicken dry and rub with 1 tbsp olive oil.
Combine paprika, cumin, garlic powder, onion powder, chipotle powder, salt and pepper in a small bowl. Massage the spice mix all over the chicken.
Heat a cast-iron skillet over medium-high. Add remaining oil and sear chicken 3–4 minutes per side until golden. Lower heat to medium, cover, and cook 6–8 more minutes until internal temp hits 165°F.
Transfer chicken to a plate to rest. Meanwhile, pulse pistachios, cilantro, lime juice, olive oil, jalapeño and water in a food processor until chunky.
Slice chicken and spoon over pistachio salsa. Serve warm.
