Hi syediz1 - I have just raided the wife's purse and found a receipt from a few months back but it may help :

QR 12 for 1kg of Australian beef
QR 21 for 4 fresh chicken breasts. ( I think whole chickens are cheaper but tend to be very small)
QR 22 for 18 eggs
QR 9 for a 800g sliced bread
QR 12 for 500g spreadable butter
Potatoes, carrots and onions all look fairly cheap although I don't know the weights on this bill! I do know that bananas are really cheap though.

Carrefour also have their own brand of products which are usually cheaper if you cn tolerate the taste... However I recommend their broccoli soup!
Not sure about rice as we tend to buy small packets but I see a good variety in big sacks that would last me a lifetime!

I note from your last post that you will be earning a salary of 5k/ month. In my opinion you won't have much left if you are looking for a bit of a social life but good luck anyhow.
