Drizzle olive oil over the whole griddle. Place the baguette rounds on one side and flip to coat both sides with olive oil. Let the slices cook for 3-4 minutes, turn halfway through.
Put the tomatoes on the other side of the griddle, season them with rosemary, garlic powder, salt, and pepper. Cook for 5 minutes.
Spread a light coat of goat cheese over each baguette slice. Put 1 tbsp of the tomato mixture on top of each slice.
Drizzle balsamic glaze over the whole platter and top with parsley.
