Place the bread on a baking sheet. Spoon minced garlic onto each piece of bread, spreading it evenly with the back of the spoon.Broil on high for 3 to 4 minutes or until lightly toasted.
Grate the tomatoes over a bowl, collecting the juices.
Top each slice of bread with a healthy portion of grated tomato. Then, lightly drizzle each piece of bread with olive oil and sprinkle with flaky sea salt.
Notes
Toasting the bread:Make sure the bread isn't too close to the heating element in your oven so you don't burn the bread. The perfect texture for pan con tomate is a light, crunchy toast to the very top of the bread - just enough for the inside to stay fluffy and soak up all the tomato juice.
