Grate tomatoes and spoon 'em over garlicky grilled bread, that's the gist.
Grill the bread (or skip this step and just toast it)
- Preheat grill or grill-pan to medium high.
- In small bowl, combine melted butter and olive oil. Brush both sides of each slice of bread with butter and olive oil mixture.
- Using tongs, arrange bread over grill grates or grill pan and let sit for 1-3 minutes, flipping once there are char marks. Repeat on other side and remove from heat when done.
Rub garlic on bread
- Slice tip off top of garlic clove and while bread is still warm, rub sliced garlic clove on top side of each piece of bread.
Make the grated tomato sauce
- On a box grater, grate tomatoes into large bowl, discarding skins. Stir in olive oil and season generously with kosher salt.
- Taste and adjust, seasoning again with kosher salt if it needs an extra punch of flavor.
Finish + serve
- Cut each slice of toast in half at an angle to create 6 smaller portions, or keep as is for 3 larger tartines, and arrange on serving platter.
- Spoon few spoonfuls of tomato mixture over each slice. Depending on the size of the tomatoes used, you may have extra raw tomato sauce - store any leftover sauce in an airtight jar in the fridge.
- Tear fresh basil and scatter over toasts, sprinkle all with flaky salt, and enjoy.
