Preheat oven to 350 degrees.
In a food processor or blender, puree the garlic cloves, Italian seasoning, & enough olive oil to make a spreadable paste.
Mix 1/4 of the garlic oil mixture in a small bowl with 1/2 cup of the raspberry chipotle sauce. In a large bowl, combine the sweet potatoes with the sauce mixture. Set aside.
Season the pork roast with salt & pepper; sear quickly on all sides in a hot pan. Place in a 9x13 baking pan & rub the remaining garlic oil mixture all over it. Pour the sweet potatoes around the pork roast. Spread the remaining 1/2 cup of raspberry chipotle sauce on top of the pork roast.
Bake uncovered - until the internal temperature reaches 145 degrees, about 1 hour. Let rest 10 minutes before slicing.
