Cut each tomato in half lengthwise and scoop out the seeds and membrane. Season the inside of each tomato shell with garlic powder, salt and pepper.
Fill each tomato shell with approx. 2 Tbsp of shredded Monterey Jack cheese and top with about 1 tsp of Parmesan cheese.
Brush the grill grates with oil, place the tomatoes on the grill and close the lid. Grill for about 4–5 minutes, just until the cheese melts. (Do not leave the tomatoes on the grill too long or they’ll become too soft and possibly collapse.)
Just before serving, place tomatoes under an oven broiler to brown the cheese.
Remove the tomatoes from the broiler and sprinkle with dried oregano and parsley. Allow the tomatoes to cool just a few minutes before serving. Enjoy!
Notes
Be a little adventurous and use heirloom tomatoes for this recipe. They are less mealy than commercially-grown tomatoes AND they look cooler!
