1. Heat oven to 400 degrees. Rub meat with oil; sprinkle with 1 1/2 teaspoons salt, 1/4 teaspoon pepper, and thyme. Roast in small pan until interior temperature reads about 160 degrees, 1 1/4 hours. Tent with foil to keep warm; let stand.

2. Melt 1 tablespoon butter in a large, shallow skillet over medium heat. Add half the apples, 1/2 teaspoon salt, and 1/8 teaspoon pepper. Saute, shaking pan to toss apples until starting to soften, about 5 minutes. Add 2 tablespoons syrup, 2 tablespoons stock or apple juice, and half the dried fruit. Saute, tossing until fruit is soft, and mixture is juicy, 2 to 3 minutes. Transfer to small bowl; cover with foil to keep warm. Repeat with remaining ingredients. Combine batches. Adjust seasoning.

3. Meanwhile, slice rolls open; spread with mustard. Slice meat into 1/4-inch-thick slices; arrange over bottom halves of rolls, and mound with hot sauce. Cover with top of rolls; place on a baking sheet. Heat until rolls are toasty and filling is hot, about 5 minutes.
