4 thoughts on “Chicken Fajitas”

  1. It’s disappointing to be on week one and get a great recipe only to read that it’s really a cycle 3 recipe. Aren’t there 7 days worth if just cycle one recipes? If not I’m really intimidated that by day 4 I’m out if options.

    • LeeAnn, if you’re talking about the fajita recipe, it IS for cycle 1. The addition of the tortilla at the end of the recipe is a SUGGESTION for Cycle 3. Use chicken if you’re on C1.
