Heat 1 tbsp oil in a large skillet over high heat. Add onions, carrots and bell peppers and cook for 2 minutes. Place vegetables in a bowl and set aside.
Heat the remaining vegetable oil in the skillet. Add the chicken, brown all sides, about 5 minutes. Add the vegetables, soy sauce, Mexico City sauce and sesame oil to the chicken and cook for 5 more minutes or until chicken is completely cooked, stirring occasionally.
Serve with a side of cauliflower rice. Provecho!
Recipe Notes
You can substitute chicken with any other protein: beef strips, sliced pork chops or tofu.
