They can't fool me. If feta cheese crumbled is $1 more for 2 ounces less than block feta, I buy the block and crumble it myself. If "lite" salad dressing's first ingredient is water and is $1 higher than regular, I buy the regular and add water.
How to crumble feta cheese I was surprised there were actually “how to” sites for this. I just sliced the block and cut it up. It sort of fell apart.
