Meanwhile, heat a grill (or indoor grill, panini press, or cook over the stove in a grill pan) to 425 degrees F. In a small bowl whisk together ancho chili powder, cumin, garlic powder and 3/4 tsp salt and 1/4 tsp pepper. Pound chicken breasts to even out their thickness using the flat side of meat mallet. Brush both sides with the 1 1/2 tbsp olive oil then season both sides of chicken with the chili powder mixture (use all of it). Grill chicken until center registers 165 degrees on an instant read thermometer, about 4 minutes per side (or about 4 minutes total if using an indoor electric grill or panini press set at high heat or sear). Transfer chicken to a plate, cover and let rest 5 minutes then cut into pieces, season with more salt to taste if desired.
