Tips for Best Results
Use Fresh Ingredients
Fresh peppers and onions provide the best texture and flavor.
Slice Everything Evenly
Uniform pieces ensure that the chicken and vegetables finish cooking at the same time.
Seal Packets Well
A tight seal keeps moisture trapped inside, creating tender, juicy chicken.
Don't Overcook
Chicken breast can dry out if cooked too long. Check for doneness near the end of the cooking time.
Add Fresh Lime Before Serving
Fresh lime juice brightens all the flavors and makes the dish taste fresher.
