God's food laws are a good thing, but I admit I don't get the meat+dairy prohibition. I know the verse; I just don't get that particular interpretation. Ah well. I do like cheeseburgers. And surely the meat in the grocery is not being slaughtered appropriately, so it is traif as well.
Hosea 6:6 For I desired mercy, and not sacrifice; and the knowledge of God more than burnt offerings.
If you're referring to:
Exo 23:19 The first of the firstfruits of your land you shall bring into the house of Jehovah your God. You shall not boil a kid in its mother's milk.
I read an interesting analysis of this that asserts that this was only in regards to sacrifices (which it seems to be reading the whole chapter) and that the Jews have basically taken it (wrongly) to mean that you can't eat meat and dairy together just in case the dairy you're eating happens to be from the mother of the meat you're eating.
