While I love any quick summer snack, this one has to be my all-time favorite. It's so simple, and while I stray from the traditional Spanish technique, the result is just as easy and delicious.
Toast 2 slices of bread to your preferred doneness, set aside.
Use a microplane to grate 1/2 of a heirloom tomato into a bowl, discard the skin. Grate in the garlic and mix. Give the basil leaves a few smacks to release their aroma, then roughly tear into the bowl.
Season with 1/2 teaspoon of flaky salt and drizzle in 2 tablespoons of olive oil. Taste and add more salt or olive oil as preferred.
Spread this tomato mixture across the two slices of toast and eat immediately.
