I want fajitas for one of my meals when I go camping this weekend. I have some frozen chicken breasts. I was planning on putting the frozen chicken in a zip lock with marinade on Thursday morning; keep it on ice in a cooler, and then eating it on Saturday for lunch. 2 ½ days of marinating… hmmm, is that too long? And can anyone suggest a marinade for chicken fajitas; keeping in mind the length of marinating time?
