Wash, dry, and dice the tomatoes (remove the hard, green parts from the center).

Transfer the tomatoes to a saucepan and bring to a boil. Stir occasionally. As soon as it boils, add the olive oil and the peeled and crushed garlic. Season with salt, pepper, and dried basil to taste. Mix well. Cook for another 3 minutes, stirring occasionally.

Transfer to a mug.
