Another thing I use as a snack is asda or morrisons or even tesco value range cooked ham in the pack. A slice is only about 15 cals, but also a good part of protein . . .I had 4 slices today for lunch, 60cals but 11g of protein and it was all I needed. If I find that Im going to "pick" or graze, then I will have a slice of the ham.
