I love summertime and spending lots of evenings on the deck grilling dinner. There’s no scented candle in existence that smells as good as grilled food!

Right now it is 109F degrees outside and last night it was still 100F at 10 pm. Crazy! The last time I grilled in this kind of heat I got blisters on my palms from grabbing the chrome handles to open the grill up! And, as I was trying to Instagram the process my phone stopped working because it overheated. So, when it’s like that I stick to the inside as much as possible.

This easy, oven baked, fajita chicken recipe is a no brainer. It’s super low in carbs and it tastes SO good! The smoked paprika I use in the seasoning even adds that little punch of smoky flavor to the chicken. I like to slice the meat and top a salad with the chicken and vegetables – or just eat as is with some cauli-rice on the side.

I’d figure 2 servings per pound for a normal appetite.
