re: Give me your best pork loin recipe.

spiral cut then stuff with mixture of fresh minced garlic, Parmesan,Italian bread crumbs and fine chopped artichoke hearts(add some spinach if you'd like)use a little Extra Virgin Olive Oil to hold the mixture together(like a paste)

then make the best homemade red gravy you know how...
note:if you don't have the time, use a couple jars of your favorite sauce(not as good)bertoli makes a good organic garlic basil that sams club sells if you must take a short cut.

put in an oblong crock pot and slow cook for a few hours...

We are talking about a pork loin and not the tenderloin correct?

edited... forgot the Parmesan and olive oil
