cheezel,
for cheese to spread on cheese, you can buy the spreadable cheese from kraft, easier than the cheddar cheese.
Wonder baby,
I use cheddar slices in melted cheese for pasta or the cauliflower. though there is salt content in cheese, but i usually buy those cheese with the healthier choice symbol, the sodium content is lower and calcium content higher than products without the healthier choice.
But i am thinking of trying those block cheese, and cut if required. I have yet to check whether the nutrient values are better in the block cheese. IF you are interested, I can update here when i found out.
