# Expert Advice:

01 -
  • One pan means one mess, and honestly, that alone changed my weeknight life.
  • Chicken comes out juicy and tender while peppers caramelize into something almost sweet.
  • The whole thing comes together in 40 minutes, which beats most takeout times if you factor in traffic.
02 -
  • Don't crowd the pan or everything steams instead of roasts—give your ingredients breathing room.
  • Check that chicken with a fork to make sure it's cooked through; undercooked chicken isn't worth any shortcut.
03 -
  • Slice your peppers and onions while the oven preheats so you're not scrambling when it's hot.
  • A squeeze of lime over everything right after it comes out of the oven brightens flavors in a way that changes everything.
