Season both sides of chicken with salt and black pepper. In a large skillet, heat oil over medium-high heat. Add chicken and cook 2 minutes per side until golden brown.
In a medium bowl, whisk together coconut milk, green chilies, curry powder, garam masala, and cumin. Add mixture to chicken and bring to a simmer. Simmer 5 minutes, until chicken is cooked through and sauce reduces slightly. Spread couscous onto a serving platter, top with chicken and garnish with cilantro.
