Which subway sandwiches did you have? I mean not all are low calorie. I think the roasted chicken sandwich is low calorie & maybe the turkey one.
A low calorie sandwich means u have all the veggies + low fat cheese + meat (roasted chicken or turkey breast or which ever one) + all sauces (except mayonnaise). Right?
Also, the subway diet would be pretty expensive. I mean approximately Rs. 450+ or 5 pounds+ everyday.
