Preheat the oven to 400 degrees. Lay the bread slices on a baking sheet and drizzle with olive oil. Top them with sea salt and place in the oven. Bake for 7-10 minutes then flip them and drizzle the other side with olive oil.
Bake for 3-5 more minutes or until they're crispy and browned. Top with basil tomato salad if desired.
