# Expert Advice:

01 -
  • One pan means one pan to wash, which is honestly the best kind of dinner magic.
  • The chicken stays juicy while the peppers get those caramelized edges that make you feel like you know what you're doing.
  • It tastes like you spent hours in the kitchen when you really just assembled ingredients and let time do the heavy lifting.
02 -
  • Don't skip stirring halfway through—the vegetables in the middle of the pan need that moment to find the heat, and the ones on the edges need a break from getting too dark.
  • Thin, even cuts of both chicken and vegetables are non-negotiable; thick pieces won't cook in the same time and you'll end up with some overdone and some underdone.
  • Warming your tortillas right before serving makes all the difference between a floppy disappointment and something you actually want to eat.
03 -
  • Cut everything as thinly and evenly as you can manage—uniformity means even cooking, which means nothing is raw or overdone.
  • Don't be shy with the lime juice; it's what keeps the chicken tender and bright, and it's hard to overdo it.
