Dinner tonight: chicken fajitas

I'm working late and have plans to attend a play later, so it's this quick recipe to the rescue for dinner tonight: Serrano-Lime Chicken Fajitas. I don't have a serrano pepper, so I'll use jalapeno; crushed red pepper flakes would also work. Regular onion would sub for red onion, and I prefer red bell peppers to green, so those will go in too. And I'm a huge fan of Santa Cruz Organic Lime Juice (and their Lemon Juice, too); in my experience, it's the nearest thing to fresh-squeezed lime juice out there, and way more convenient.
