Prepare the Tomatoes: Select large, ripe tomatoes that are firm yet slightly soft to ensure they hold up during marination. Rinse them under cold water and pat dry with a paper towel to remove any excess moisture.
Slice the Tomatoes: Slice the tomatoes into wedges, rounds, or cubes based on your preference, ensuring uniform sizes for even marination.
Make the Marinade: In a separate bowl, combine olive oil and balsamic vinegar until well mixed. Add in sea salt, black pepper, and minced garlic to create an aromatic blend.
Combine Ingredients: Stir in chopped fresh basil and parsley, along with red pepper flakes if desired. Whisk everything together before pouring it over the sliced tomatoes.
