Today, I made pretty much the exact thing I made yesterday (Chicken Pepper Skillet) except I roasted the peppers instead of saute-ing them. The best description on how to roast peppers is at this link.
You must try!
I then put 1/3 cup cheese with the red pepper/chicken mix, put it in a whole wheat tortilla, and grilled it to perfection. All for under 500 calories! And that's with salsa and a handful of chips!!
