Put a skillet on at medium high and add some olive oil. Break out the chicken slices and put ’em in the pan.
Sprinkle with some salt and pepper and toss a few times as the chicken thaws and starts to grill.
While the chicken is doing it’s stuff seed the poblano and the jalapeño peppers and cut them into strips . If you don’t want it to be too spicy just go with green bell peppers. Cut the onion into strips.
