A "white" lie to me is: Honey this pot roast is delicious. When I know for a fact that it's too salty or over cooked. There is no victim, no major damage should I find out that he did find my roast too salty.

As TheB suggested, I'd have a serious talk with him. Let him know that by choosing to lie to you, whatever the reason, it makes you uncomfortable. I'd find this behavior sneaky and very suspect. If there's no reason to worry then there's no reason to lie.
