I have to say I quite like the Old El Paso range of products and we particularly like their fajita packet spice mix. Me being me, I can't help but deviate from what you're 'supposed' to do and as the spice mix is included in their fajita meal kit I took it out and dabbled.
I cooked sliced chicken fillets in a little oil in a hot frying pan. The chicken becomes glazed and is smokey and delicious. Add sliced peppers and onions to the pan stirring for a couple of minutes and serve with shredded lettuce, cucumber and top with either soured cream or guacamole then tuck in.
One Pan Rice Meals 'Chilli and Garlic' for Chicken - all you do is add sliced pepper, onion and chicken. There's also a Family Friendly, Extra Mild One Pan Rice Meal too which is great if you don't like it hot!
