About this Recipe

Modified from:


4 garlic cloves
1 1/2 tsp coarse kosher salt
1/4 cup fresh parsley
6 tbsp extra-virgin olive oil
2 tsp dried basil
2 tsp dried oregano
1 tsp dried rubbed sage
1 tsp fennel seeds, ground in mortar with pestle or spice grinder
1 tsp ground black pepper
9 lbs pork shoulder
1 tbsp red wine vinegar
1 lb onions, halved, cut into 1/4-inch-thick slices
1 lb red bell peppers, seeded, cut into 1/2-inch-wide strips
1/2 lb green bell peppers, seeded, cut into 1/2-inch-wide strips
1 1/2 lbs fresh mozzarella cheese, thinly sliced
1 tbsp cornstarch
1 Pkg Dempster's Deluxe White Hamburger Buns


For pork:

Chop garlic on work surface. Sprinkle with 1 1/2 teaspoons kosher salt and mince until paste forms. Transfer paste to small bowl; mix in parsley and next 7 ingredients. Using small sharp knife, make 20 evenly spaced 1-inch-long, 2-inch-deep slits in pork. Stuff seasoning mixture into slits. Sprinkle outside of pork with salt and pepper. Let stand 1 hour for seasonings to penetrate.

Place pork in slow cooker on low for 7 hours.

Pour leftover juices from roasting pan into 4-cup measuring cup. Spoon off fat. If necessary, add enough water to degreased juices to measure 2 cups. Stir 2 tablespoons juices and cornstarch in small saucepan until cornstarch dissolves; whisk in remaining juices and vinegar. Whisk over medium heat until sauce boils and thickens, about 2 minutes. Season to taste with salt and pepper.

For vegetables:

Heat oil in heavy large skillet over medium-high heat. Add onions and all peppers; sauté until vegetables are tender and brown, stirring occasionally, about 30 minutes. Sprinkle with salt and pepper.

Arrange Dempster's Deluxe White Hamburger Bun bottoms on work surface; mound with warm pork and drizzle with sauce. Cover with cheese, vegetables, and bun tops. Serve warm.

Do-ahead tip:

The pork, sauce, and vegetables can be made one day ahead. Cover and refrigerate everything separately. Before serving, reheat pork, covered, in 350°F oven about 40 minutes; rewarm sauce and vegetables over medium heat.
