When are chicken fajitas done and ready to serve?
To be safe, the internal temperature of the chicken needs to reach 165° internal temperature when measured with an instant-read thermometer, and the vegetables should be tender with some char.

How to store and reheat leftover fajitas
Store leftovers airtight in the refrigerator for 3 days. Freezing is not recommended due to texture issues with the cooked vegetables.
Reheat leftover fajitas on the stovetop with a covered skillet over medium heat. Add a bit of vegetable oil and stir occasionally. It will take about 5 minutes or a bit more.
❓FAQs
Red wine vinegar may not be in your pantry. It has a pleasant, not-in-your-face taste for things like salads.
If you don't have red wine vinegar, you can substitute some apple cider or rice vinegar, but not at the same volume. Do about a third to half the volume and taste test it. Vinegar can overwhelm a dish quickly.
No, not a good idea. It will dry out during cooking, and we want the marinade with the raw chicken.
Yes, use a large skillet or griddle over medium-high or high heat.

Step-by-Step Photo Instructions
Preheat the grill with a griddle or large grill pan in place on high. Add vegetable oil just before cooking. The grill lid should be open for this entire recipe.
In a medium bowl, whisk all marinade ingredients together.
Clean and cut the chicken into strips across the grain.
Add chicken to the marinade for 10 to 30 minutes. Mix well and let sit at room temp while dealing with veggies.
Cut onion and peppers and coat with 1 tablespoon olive oil and ¼ teaspoon salt.
After the grill is preheated for at least 10 minutes, add oil and place vegetables on the griddle. Stir occasionally and cook for about 6 minutes until it starts to brown and soften. If browning too fast, turn down the heat or move to a cooler part of the grill.
Push the veggies to the side and place the chicken on the griddle, stirring both the chicken and vegetables occasionally. Cook for about 6-8 minutes until you can cut the chicken with a wooden spoon and an internal temperature of 165°. The exact time will vary with the grill, the griddle, and the thickness of the chicken.
Mix in vegetables back into the chicken and stir well.

Recipe Notes
Pro Tips:
- This recipe is unusual in that the grill lid is left open.
- This needs about 1 ½ pounds of chicken, I chose skinless boneless chicken breasts, but thighs would work great.
- Cut across the grain of the meat as much as possible.
- If you don't have red wine vinegar, you can substitute some apple cider or rice vinegar but not at the same volume. Do about a third to half the volume and taste test it. Vinegar can overwhelm the taste quickly.
- I buy limes frequently for recipes, but I do not normally keep them around. So I do usually keep some lime juice in the refrigerator. Or you can just slip it.
- Add a little heat with ½ teaspoon of cumin.
- Good refrigerated for 3-4 days.
- Nutrition does not include serving ingredients.

Thanks, Made this the other night but tripled the amount of onions since I didn't
have any peppers and my husband doesn't like them anyway. You know this is
a keeper when he eats the leftovers for breakfast!!

Hi Susan,
Welcome to the blog. Sorry for the delayed response.
Glad it worked well for you.
Thanks for the note and rating.

Love this recipe! Dr. Dan - where did you get that griddle for the grill? I have never seen something like that - totally awesome!
Dan Mikesell AKA DrDan says
Hi Charlene,
The griddle is just one of those toys I had to have it is cast iron (very heavy), enamel paint and non-stick surface.It takes a bit to preheat but once it is hot, it stays very hot. Easy to clean.
William Sonoma was the only place that sold them in 2011 then they disappeared a few years later. I think eBay is your only hope. There is one there now for $30 (mine was $100) but $32 shipping. I doubt you will see many of them. Search for "La Plancha Cast-Iron Griddle"

Susan Bostaph says
This looks wonderful !
How much oil do you put in the heated pan? Will be making this in a cast iron frying pan on the stove. (I'm assuming the oil is in addition to the 2T in the marinade - Vegetable oil ?)
Thanks.
Dan Mikesell AKA DrDan says
Hi Susan,
Welcome to the blog.
You're right. I didn't specify. Just enough to lightly cover the surface of the pan or griddle. About a tablespoon usually is enough. A stovetop cast iron is a great choice.
In the middle of this recipe is a list of other fajita recipes. There is a slightly different stovetop recipe there that is a bit more complicated with more ingredients. I tend more to this simpler recipe.

Love this recipe. I didn't have red wine vinegar so I used lemon juice instead. It was great.
DrDan says
Hi Barbara,
I haven't done this on the grill for a while. I'm scheduling for next week.
Thanks for the note.

Cathy says
This is an excellent marinade. I marinaded the chicken for a bit over an over and put thighs on the grill and sliced them after they were cooked. It was delicious! We will definitely have this again.
DrDan says
It is quite tasty...
Thanks for the comment

Chris should probably add some cumin but they are just right for kids and old people like me. The griddle is nice and very heavy. I see very little reason to cook inside if it's not raining this summer.
