In a large skillet, heat oil on medium. Add garlic and cook for 30 seconds. Add chicken and saute until cooked through, about 7 minutes. Transfer chicken to a plate. To skillet, add tomatoes, olives, capers, sea salt, black pepper, chile powder, cayenne and paprika. Cook for 5 to 7 minutes or until heated through. Add sweet potato noodles and Swiss chard, stirring to combine. Cook until sweet potato noodles are tender and Swiss chard is wilted, about 5 to 7 minutes more. Return chicken to skillet and heat through.
