Chicken fajitas are a Tex-Mex dish that consists of marinated chicken, bell peppers, and onions that are cooked on a hot skillet or grill. The chicken is marinated in a mixture of lime juice, garlic, cumin, and chili powder, which gives it a tangy and spicy flavor. The vegetables are cooked until they are tender and slightly charred, and then served with the chicken on warm tortillas. Chicken fajitas are typically served with toppings such as sour cream, guacamole, and salsa.
