Slice onion in half, exposing rings. Then make thin vertical slices. Feel free to cut rings in half or smaller slices if desired. I only use ~1/3 of the onion

Cut bell pepper into thin slices 1/4" wide. I cut these slices in half lengthwise to make em shorter. Use ~3/4 of bell pepper

Cut open jalapeno, remove seeds, and dice as much heat as desired. I'd recommend 1/2 for a lil heat, and the whole thing if you wanna take a walk on the wild side

In large skillet add oil, bell pepper, onion, and jalapeno. Grill on medium/med-high flame

While veggies grill, cut chicken into strips of desired size. I go with 1/2" wide,~1.5" long

When onions are translucent, and veggies have a little browning, remove to plate

Reusing the SAME pan, add a splash more oil ( 1/2 tbsp) and throw in chicken.

Add spices, squeeze lime over, and grill over medium flame for approx 10 minutes (this will take longer if you didn't get thin cut chicken)

Once chicken is cooked, add veggies back to pan with chicken to reheat (3-5 mins) and squeeze any juice still in lime

Serve in warm tortillas w/ rice, beans, and maybe some guac or lite amount of pepper jack cheese!
