My favorite low calorie recipe is to cook a boneless skinless chicken breast with some cilantro and cumin. I then shred it and put it over shreded lettuce with lime juice, black beans and grape tomatoes. If I want to add a bit more calories to it I will add a few slices of avacado and some fat free shredded cheddar.
This is my absolute favorite dinner. Sometimes I will make it without the chicken and just have it with the beans.
