Chinese take-out and homemade chicken tortillas/fajitas. I use the Dempster's tortilla wraps and they're only 150 calories each, which makes them the perfect low-cal food holder. Here's what I put in the wraps:
Sliced chicken breast (boneless, skinless. 3 chicken breasts makes 5 large wraps) lightly seasoned with Seasoning Salt for a nice flavor
Fresh mushrooms sliced fairly thinly and cooked in (about) 1 Tbsp. Becel margarine
Shredded cheese (120 calories for a third of a cup, we don't use more than that)
Chopped tomatoes
Fried diced onions
Rough estimate puts each wrap at about 300 calories... And considering I'm very stingy with my breakfast and lunch calories, when I eat 2 or 3 of those I don't feel the slightest bit guilty.
