I've only had the Slim-a-Bear sandwiches, since I like the "Healthy" Blue Bunny ice cream bars since the nutritionals are more respectable.
But the Slim-a-Bear sandwiches (whether you get no sugar added or 100 calorie kind) are really good and satisfying for just 100 calories. They have 2g fiber and 3-10g sugar. They are really low-fat too.
There's a little calcium in them.
Other 100 calorie products...
English Toffee / French Vanilla Bars

Vanilla and Chocolate Sandwiches - ***** (I like the chocolate on chocolate. :)
