4 canned whole tomatoes , about 1 cup
1 garlic clove
1/2 teaspoon sea salt 
1 tablespoon fresh basil, chopped
3 tablespoons extra virgin olive oil 
1 tablespoon red wine or sherry vinegar
Freshly cracked pepper (optional)
Baguette or other desirable bread
Chop or purée the tomatoes and put them in a small bowl.
Mince the garlic, then pour the salt on top of it. Drag the side of your knife over the garlic-salt mix until it becomes mashed like a paste, below. (You can simply leave it minced, but as a paste the garlic “disappears” into the sauce.)
Add the basil, olive oil, vinegar, and pepper (if using). Mix and set aside, covered, for at least a half-hour to marinate.
Slice and toast the bread. Generously spread the tomato mixture onto each slice and serve.
