Easy Fajitas

I mean really easy:

• Frozen precooked, pre-sliced, grilled chicken breast (I purchased this wonderful find from ALDI and used maybe 3/4 of a 2- to 3-lb. bag)
• Frozen bag of sliced peppers and onions (Probably 12 oz. Sorry, I'll have to pay attention to quantities and sizes more!)
• 2 tablespoons canola oil
• Garlic powder to taste
  
• Small corn tortillas
  

Heat the oil and add the chicken and vegetables. Stir until everything is coated with the oil. Add the garlic powder. Cover the mixture but check back regularly to stir. Cook until the meat and veggies are thawed and everything is heated through, not more than 15-20 mins.
Heat the tortillas in the microwave and add the meat and veggies mixture. Voila! I guesstimate the meat/veggies mixture is enough for about 10 fajitas.
