Making the Best Marinated Tomatoes Salad is as simple as following these easy steps:

1. Prepare the Tomatoes: Wash the tomatoes thoroughly. Remove the cores and chop them into bite-sized pieces.
2. Slice the Onion: Thinly slice the red onion, ensuring the pieces are uniform for even marination.
3. Chop the Basil: Wash and chop the fresh basil leaves into small pieces to release their fragrance.
4. Mix the Marinade: In a medium bowl, whisk together the olive oil, balsamic vinegar, minced garlic, salt, and pepper until well combined.
5. Combine Ingredients: In a large salad bowl, add the chopped tomatoes, sliced onions, and chopped basil.
6. Add Marinade: Pour the dressing over the tomatoes and gently toss everything together until all ingredients are well coated.
7. Marinate: Let the salad sit for at least 30 minutes at room temperature to allow the flavors to meld, although it can be marinated longer for richer taste.
8. Taste and Adjust: Before serving, taste the salad and adjust seasoning with extra salt, pepper, or vinegar if needed.
9. Serve: For an added touch, crumble feta cheese or add mozzarella just before serving.

These simple steps will guide you in creating this incredible salad quickly and effortlessly.
