Prepare grilled tomatoes

1. Cut tomatoes in 4 equal slices
2. Brush with olive oil, sprinkle with salt and pepper
3. Cook slices on a grill or in a cast iron pan over very high heat. Your grill should be very hot to avoid sticking.

Prepare parmesan rounds

1. Generously sprinkle freshly grated parmesan cheese on a cookie sheet covered with parchment paper to form a circle or oval approximately 10 cm wide
2. Bake for 2 to 3 minutes at 180° C or 350°F. until cheese turns golden brown
3. Once parmesan rounds are cooked, wait a few minutes before removing them from the cookie sheet (Note: rounds are very fragile and must be handled with care.)

Prepare vinaigrette

1. Mix all vinaigrette ingredients (orange juice, lemon juice, vinegar, oil, salt, and pepper)

Presentation

1. Lay a slice of cheese (optional) on top of each grilled tomato slice and top with a crunchy parmesan round
2. Pour a thin circle of vinaigrette around each tomato, cheese, and parmesan round arrangement and serve the remaining vinaigrette in a bowl to accompany your refreshing appetizer
