Spinach-stuffed veal chops

For the stuffing:
1 tablespoon extra-virgin olive oil
1/2 cup finely chopped yellow onion
2 teaspoons minced garlic
2 plum tomatoes, cored, seeded, and chopped
1 package (10 ounces) frozen chopped spinach, defrosted and squeezed very dry
3 slices prosciutto (about 2 ounces), finely chopped
1/2 cup coarsely grated fontina cheese
1/2 teaspoon kosher salt
1/4 teaspoon freshly ground black pepper
For the rub:
2 teaspoons finely chopped fresh rosemary
1/2 teaspoon kosher salt
1/2 teaspoon freshly ground black pepper
4 veal loin chops, about 3/4 pound each and
1-1/4 to 1-1/2 inches thick
Extra-virgin olive oil

1. To make the stuffing: In a large saute pan over medium heat, warm the olive oil and cook the onion until soft, 5 to 6 minutes. Add the garlic and cook for 1 minute more. Add the tomatoes and cook for 3 minutes, then add the spinach and cook for 2 minutes. Remove from the heat and allow to cool for 3 or 4 minutes, then add the remaining stuffing ingredients. Divide the stuffing into four portions.
2. To make the rub: In a small bowl combine the rub ingredients.
3. Trim the chops of any excess fat and cut a pocket in the side of each chop. Push the stuffing into the pockets and close with toothpicks. Lightly brush or spray the chops with olive oil and season with the rub. Allow to stand at room temperature for 20 to 30 minutes before grilling.
4. Grill over Direct Medium heat until medium rare, 15 to 20 minutes, turning once halfway through grilling time. Remove from the grill and allow to rest for 3 to 5 minutes. Serve warm.
