Heat 1 tablespoon olive oil in a large frying pan over high heat. Add peppers and onions. Toss to coat, and cook for about 5 minutes, stirring occasionally until peppers soften and begin to brown slightly.
Place the chicken in a small mixing bowl and drizzle with remaining oil. Sprinkle the chicken with the taco seasonings and add the lime juice. Toss well to coat chicken thoroughly. Add the chicken to the pan with the peppers and onions, and reduce heat to medium. Stir to combine everything with the seasoning.
Continue cooking, stirring occasionally, until the chicken has cooked through, about 3 to 4 minutes. Serve with tortillas and toppings of your choice
